    Abstract: A magnetic read transducer is described with a magnetoresistive sensor that has a free layer, and an antiferromagnetically-coupled (AFC) soft bias layer for magnetically biasing the free layer. The free layer has a first edge in a track width direction along an air-bearing surface (ABS). At least a portion of the AFC soft bias layer is conformal to at least a portion of a second edge of the free layer, and situated to form a magnetic moment at an angle with respect to a center line of the free layer. The center line of the free layer extends in the same direction as the free layer first edge that is in the track width direction along the ABS.

    Abstract: An MRAM array of MTJ memory cells is provided wherein each such cell is a layered MTJ structure located at an intersection of a word and bit line and has a small circular horizontal cross-section of 1.0 microns or less in diameter and wherein the ferromagnetic free layer of each such cell has a magnetic anisotropy produced by a magnetic coupling with a thin antiferromagnetic layer that is formed on the free layer. The array of MTJ memory cells so provided is far less sensitive to shape irregularities and edge defects of individual cells than arrays of the prior art.

    Abstract: A three-layer magnetic element comprises, on a substrate, a first oxide, hydride or nitride layer O having a metal magnetic layer M mounted thereon, the latter having either a second oxide, hydride or nitride layer O′, or a non-ferromagnetic metal layer M′ mounted thereon. Layer M is continuous, has a thickness of 1 to 5 nm and the magnetization thereof is parallel to the layer plane in the absence of layers O and O′. There is, for a range of temperature equal to or greater than ambient temperature, interfacial magnetic anisotropy perpendicular to the layer plane on interfaces O/M and M/O′ that is capable of decreasing the effective demagnetizing field of layer M or orienting the magnetization of layer M in a manner substantially perpendicular to the layer plane.

    Abstract: Graphene magnet multilayers (GMMs) are employed to facilitate development of spintronic devices. The GMMs can include a sheet of monolayer (ML) or few-layer (FL) graphene in contact with a magnetic material, such as a ferromagnetic (FM) or an antiferromagnetic material. Electrode terminals can be disposed on the GMMs to be in electrical contact with the graphene. A magnetic field effect is induced in the graphene sheet based on an exchange magnetic field resulting from a magnetization of the magnetic material which is in contact with graphene. Electrical characteristics of the graphene can be manipulated based on the magnetization of the magnetic material in the GMM.
