Patent number: 7477491Abstract: It has been found that the insertion of a copper laminate within CoFe, or a CoFe/NiFe composite, leads to higher values of CPP GMR and DRA. However, this type of structure exhibits very negative magnetostriction, in the range of high ?10?6 to ?10?5. This problem has been overcome by giving the copper laminates an oxygen exposure treatment When this is done, the free layer is found to have a very low positive magnetostriction constant. Additionally, the value of the magnetostriction constant can be adjusted by varying the thickness of the free layer and/or the position and number of the oxygen treated copper laminates.Type: GrantFiled: November 7, 2005Date of Patent: January 13, 2009Assignee: Headway Technologies, Inc.Inventors: Min Li, Kunliang Zhang, Masashi Sano, Koichi Terunuma, Simon Liao, Kochan Ju

Patent number: 7400475Abstract: Patterned, longitudinally and transversely antiferromagnetically exchange biased GMR sensors are provided which have narrow effective trackwidths and reduced side reading. The exchange biasing significantly reduces signals produced by the portion of the ferromagnetic free layer that is underneath the conducting leads while still providing a strong pinning field to maintain sensor stability. In the case of the transversely biased sensor, the magnetization of the free and biasing layers in the same direction as the pinned layer simplifies the fabrication process and permits the formation of thinner leads by eliminating the necessity for current shunting.Type: GrantFiled: January 14, 2005Date of Patent: July 15, 2008Assignee: Headway Technologies, Inc.Inventors: Cheng T.

Patent number: 7201947Abstract: As track widths of magnetic read heads grow very small, conventional longitudinal bias stabilization has been found to no longer be suitable since the strong magnetostatic coupling at the track edges also pins the magnetization of the free layer. This problem has been overcome by extending the free layer so that it is no longer confined to the area immediately below the spacer or tunneling layer. A longitudinal bias layer immediately below the free layer is given a relatively weak magnetic exchange coupling field of about 200 Oe. Although there is strong exchange coupling between this and the free layer, the degree of pinning of the free layer is low so that the device's output signal is reduced by less than about 10%. A process for manufacturing both the CPP SV and a MTJ versions of the invention is described.Type: GrantFiled: September 10, 2002Date of Patent: April 10, 2007Assignee: Headway Technologies, Inc.Inventors: Simon Liao, Kochan Ju, Youfeng Zheng

Patent number: 7184248Abstract: A patterned, synthetic, longitudinally exchange biased GMR sensor is provided which has a narrow effective trackwidth and reduced side reading. The advantageous properties of the sensor are obtained by satisfying a novel relationship between the magnetizations (M) of the ferromagnetic free layer (F1) and the ferromagnetic biasing layer (F2) which enables the optimal thicknesses of those layers to be determined for a wide range of ferromagnetic materials and exchange coupling materials. The relationship to be satisfied is MF2/MF1=(Js+Jex)/Js, where Js is the synthetic coupling energy between F1 and F2 and Jex is the exchange energy between F2 and an overlaying antiferromagnetic pinning layer. An alternative embodiment omits the overlaying antiferromagnetic pinning layer which causes the relationship to become MF2/MF1=1.Type: GrantFiled: November 1, 2005Date of Patent: February 27, 2007Assignee: Headway Technologies, Inc.Inventors: Min Li, You Feng Zheng, Simon Liao, Kochan Ju

Patent number: 7180716Abstract: A method for fabricating a stitched CPP synthetic spin-valve sensor with in-stack stabilization of its free layer. The method can also be applied to the formation of a stitched tunneling magnetoresistive sensor. The free layer is strongly stabilized by magnetostatic coupling through the use of a longitudinal biasing formation that includes a ferromagnetic layer, denoted LBL, within the pillar portion of the sensor and a synthetic exchange coupled tri-layer within the stitched portion of the sensor. The tri-layer consists of two ferromagnetic layers, FM1 and FM2 separated by a coupling layer and magnetized longitudinally in antiparallel directions. A criterion for the magnetic thicknesses of the layers: [t(LBL)+t(FM1)]/t(FM2)=70/90 angstroms of CoFe insures a strong exchange coupling. The magnetization of the tri-layer is done in a low field anneal that does not disturb the previous magnetization of the ferromagnetic free layer.Type: GrantFiled: March 30, 2004Date of Patent: February 20, 2007Assignee: Headway Technologies, Inc.Inventors: Min Li, Youfeng Zheng, Kunliang Zhang, Simon Liao, Kochan Ju

Patent number: 7170720Abstract: It is known that the magnetic shields, between which CPP GMR stacks are sandwiched, can be a source of AMR (anisotropic magneto-resistance) noise. This has been significantly reduced by coating both the magnetic shields with highly conductive layers. If the guidelines disclosed in the invention are followed, the read head can exhibit AMR noise reduced by about 14 to 20. Additionally, the total thickness of the read gap can be maintained to be as low as 300 to 400 Angstroms.Type: GrantFiled: August 28, 2003Date of Patent: January 30, 2007Assignee: Headway Technologies, Inc.Inventors: Charles C. Lin, Min Li, Simon Liao

Patent number: 7162791Abstract: Currently, in a process of manufacturing a top spin valve structure, the shield-to-shield separation of a spin valve head cannot be below about 800 ?, mainly due to sensor-to-lead shorting problems. This problem has now been overcome by inserting a high permeability, high resistivity, thin film shield on the top or bottom (or both) sides of the spin valve sensor. A permeability greater than about 500 is required together with a resistivity about 5 times greater than that of the free layer and an MrT value for the thin film shield that is 4 times greater than that of the free layer.Type: GrantFiled: December 14, 2004Date of Patent: January 16, 2007Assignee: Headway Technologies, Inc.Inventors: Kochan Ju, Cheng Horng, Youfeng Zheng, Simon Liao, Jei-Wei Chang

Patent number: 7141314Abstract: A current-perpendicular-to-plane (CPP) giant magnetoresistive (GMR) sensor of the synthetic spin valve type and its method of formation are disclosed, the sensor including a novel laminated free layer having ultra-thin (less than 3 angstroms thickness) laminas of Fe50 Co50 (or any iron rich alloy of the form CoxFe1?x with x between 0.25 and 0.75) interspersed with thicker layers of Co90Fe10 and Cu spacer layers to produce a free layer with good coercivity, a coefficient of magnetostriction that can be varied between positive and negative values and a high GMR ratio, due to enhancement of the bulk scattering coefficient by the laminas. The configuration of the lamina and layers in periodic groupings allow the coefficient of magnetostriction to be finely adjusted and the coercivity and GMR ratio to be optimized. The sensor performance can be further improved by including layers of Cu and Fe50Co50 in the synthetic antiferromagnetic pinned layer.Type: GrantFiled: February 25, 2004Date of Patent: November 28, 2006Assignee: Headway Technologies, Inc.Inventors: Kunliang Zhang, Min Li, Rachid Sbiaa, Simon Liao, Yue Liu

Patent number: 7130168Abstract: Reduction of the free layer thickness in GMR devices is desirable in order to meet higher signal requirements, besides improving the GMR ratio itself. However, thinning of the free layer reduces the GMR ratio and leads to poor thermal stability. This problem has been overcome by making AP2 from an inverse GMR material and by changing the free layer from a single uniform layer to a ferromagnetic layer AFM (antiferromagnetically) coupled to a layer of inverse GMR material. Examples of alloys that may be used for the inverse GMR materials include FeCr, NiFeCr, NiCr, CoCr, CoFeCr, and CoFeV. Additionally, the ruthenium layer normally used to effect antiferromagnetic coupling can be replaced by a layer of chromium. A process to manufacture the structure is also described.Type: GrantFiled: September 16, 2005Date of Patent: October 31, 2006Assignee: Headway Technologies, Inc.Inventors: Min Li, Simon Liao, Kochan Ju
