  • Patent number: 8211557
    Abstract: A magnetic microstructure comprising (i) a magnetic storage layer having a magnetic easy axis perpendicular to a film plane of the storage magnetic layer; (ii) a magnetic assist layer having a magnetic easy axis in the film plane; and (iii) a phase transition interlayer between the magnetic storage layer and the magnetic assist layer. The phase transition layer comprises a material, such as FeRh, that switches from antiferromagnetic at ambient to ferromagnetic at a transition temperature that is greater than ambient, but below the Curie temperature. When the phase transition interlayer is in antiferromagnetic phase, there exists little magnetic coupling between the storage and assist layers. When the interlayer changes to ferromagnetic phase, the interlayer couples the magnetic moments of the storage and assist layer ferromagnetically.

  • Patent number: 7826258
    Abstract: A magnetic memory or MRAM memory system comprising an M×N crossbar array of MRAM cells. Each memory cell stores binary data bits with switchable magnetoresistive tunnel junctions (MJT) where the electrical conductance changes as the magnetic moment of one electrode (the storage layer) in the MJT switches direction. The switching of the magnetic moment is assisted by a phase transition interlayer that transitions from antiferromagnetic to ferromagnetic at a well defined, above ambient temperature.

  • Patent number: 7616412
    Abstract: A perpendicular spin-torque-driven magnetic oscillator is disclosed. According to various embodiments, the magnetic oscillator comprises a magnetic reference stack, a magnetic oscillating stack, and an interlayer between the reference stack and the oscillating stack such that the reference stack and the oscillating stack are exchange coupled. The reference stack may have sufficient perpendicular anisotropy such that it causes, via the spin momentum transfer effect, the spin polarization of the conducting electrons in the oscillating stack to produce a spin torque on the local magnetization of the oscillating layer. As such, the oscillating stack may produce a sustained gyromagnetic oscillation around the perpendicular axis of the oscillating stack when (i) the oscillating stack and the reference stack have opposite magnetizations and (ii) there is a direct current flowing in the magnetic oscillator from the oscillating stack to the reference stack.

  • Publication number: 20090022222
    Abstract: A method of obtaining a disparity vector and its encoding/decoding in the multi-view coding process is disclosed. The present invention includes essentially: determining a disparity vector between two views during the multi-view image coding, and computing a disparity vector between the other two views according to the disparity vector between the two views and the known relative location information between each of the views. Thereafter, the disparity vector is used for multi-view encoding/decoding. The present invention further makes use of the correlation between the disparity vector and depth information of the spatial vector on one hand, and on the other hand makes use of the direct relationship between the disparity vector and the location of each of the cameras. It is experimentally proved that the disparity vector between several views can be accurately computed during the multi-view coding, thereby improving the performance of multi-view coding.
