  • Publication number: 20110177258
    Abstract: A method and device disclose how to drain a liquid coating metal from the two sides of a running steel strip. The method transfers a strip coated with a liquid coating metal, as it runs at the tank outlet, from a region not subjected to a magnetic field to another region subjected to a static magnetic field generated between the poles of magnetic members arranged opposite each other on either side of the strip and having field lines, or at least a main shell of the field lines, intersecting with the strip over at least one minimum longitudinal extent so that the liquid coating metal is correlatively subjected to a magnetic field variation generating on the liquid metal a force opposite to the running direction. Due to the low field variation, this magnetic braking effect generates little Foucault current in the strip.

  • Publication number: 20110111133
    Abstract: A method by which portions of a wafer level fabrication can be selectively heated by means of the formation of a plasmon generating layers of specific size, shape, orientation and material on the fabrication and then illuminating the formation with electromagnetic radiation of such wavelength and polarization as will optimally be absorbed by the plasmon generating layers so as to generate plasmons therein. The generated plasmons thereupon produce thermal energy which is transferred to portions of the fabrication with which the plasmon generation layer has thermal contact. This method is particularly advantageous for producing multiple anneals and different magnetic pinning directions for the anti-ferromagnetic pinning layer in each of an array of GMR or TMR devices. In that process, the anti-ferromagnetic layer must be raised above its Curie temperature at which point it loses its anti-ferromagnetic properties and can have a magnetization imposed by application of an external magnetic field.

    Abstract: A hard bias (HB) structure for longitudinally biasing a free layer in a MR sensor is disclosed that is based on HB easy axis growth perpendicular to an underlying seed layer which is formed above a substrate and along two sidewalls of the sensor. In one embodiment, a conformal soft magnetic layer that may be a top shield contacts the HB layer to provide direct exchange coupling that compensates HB surface charges. Optionally, a thin capping layer on the HB layer enables magneto-static shield-HB coupling. After HB initialization, HB regions along the sensor sidewalls have magnetizations that are perpendicular to the sidewalls as a result of surface charges near the seed layer. Sidewalls may be extended into the substrate (bottom shield) to give enhanced protection against side reading. The top surface of the seed layer may be amorphous or crystalline to promote HB easy axis perpendicular growth.

    Abstract: A magnetic sensor includes a single substrate, a conventional GMR element formed of a spin-valve film including a single-layer-pinned fixed magnetization layer, and a SAF element formed of a synthetic spin-valve film including a plural-layer-pinned fixed magnetization layer. When the spin-valve film intended to act as the conventional GMR element and the synthetic spin-valve film intended to act as the SAF element are subjected to the application of a magnetic field oriented in a single direction at a high temperature, they become giant magnetoresistive elements whose magnetic-field-detecting directions are antiparallel to each other. Since films intended to act as the conventional GMR element and the SAF element can be disposed close to each other, the magnetic sensor which has giant magnetoresistive elements whose magnetic-field-detecting directions are antiparallel to each other can be small.

  • Publication number: 20040151978
    Abstract: A direct-write method and apparatus for depositing a functional material with a preferred orientation onto a target surface. The method comprises the following steps: (1) forming a precursor fluid to the functional material, with the fluid containing a liquid component; (2) operating a dispensing device to discharge and deposit the precursor fluid onto the target surface in a substantially point-by-point manner and at least partially removing the liquid component from the deposited fluid to form a thin layer of the functional material which is substantially solidified and is of a predetermined pattern; and (3) during the liquid-removing step, subjecting the deposited fluid to a highly localized electric or magnetic field for poling until a preferred orientation is attained in the deposited functional material.

  • Patent number: 6716488
    Abstract: A ferrite layer formation process that may be performed at a lower temperature than conventional ferrite formation processes. The formation process may produce highly anisotropic structures. A ferrite layer is deposited on a substrate while the substrate is exposed to a magnetic field. An intermediate layer may be positioned between the substrate and the ferrite to promote bonding of the ferrite to the substrate. The process may be performed at temperatures less than 300° C. Ferrite film anisotropy may be achieved by embodiments of the invention in the range of about 1000 dyn-cm/cm3 to about 2×106 dyn-cm/cm3.

A wide range of optical transmission (0.001% up to 20% at 193 nm) is obtained by this process. A post deposition process is implemented to obtain the desired properties (stability of optical properties with respect to laser irradiation and acid treatment) for use in industry. A special fabrication process for the sputter target is implemented to lower the defects of the film.

  • Patent number: 6632517
    Abstract: The magnetic and magnetotransport properties of field-aligned single domain half-metallic CrO2 powders have been studied. Needle-shaped nanoparticles of CrO2 have been aligned in a strong magnetic field. The aligned powder sample shows a strong anisotropy along the alignment direction. The conduction mechanism of the aligned CrO2 powder sample has been examined and is consistent with the intergranular spin dependent tunneling. Negative tunneling magnetoresistance (TMR) of about 41% is achieved in a small field in the vicinity of the coercive field at 5 K. The magnetoresistance (MR) versus field curve shows two well-separated narrow peaks at the coercive fields and resembles that of a magnetic tunnel junction. This junction-like MR results from the narrow switching field distribution of the aligned powders. The results suggest that the aligned magnetic CrO2 particles may find novel applications in spin transport structures and devices.
