摘要： A Lorentz Magnetoresistive sensor having an ultrathin trapping layer disposed between a quantum well structure and a surface of the sensor. The trapping layer prevents charge carriers from the surface of the sensor from affecting the quantum well structure. This allows the quantum well structure to be formed much closer to the surface of the sensor, and therefore, much closer to the magnetic field source, greatly improving sensor performance. A Lorentz Magnetoresistive sensor having a top gate electrode to hinder surface charge carriers diffusing into the quantum well, said top gate electrode being either a highly conductive ultrathin patterned metal layer or a patterned monoatomic layer of graphene.

摘要： A patterned perpendicular magnetic recording disk has a Co-alloy recording layer patterned into discrete data islands arranged in concentric tracks and exhibits a narrow switching field distribution (SFD). The disk includes a substrate, a NiTa alloy planarizing layer on the substrate, a nonmagnetic Ru-containing underlayer on the planarizing layer, an oxide-free Co alloy magnetic recording layer, and an ultrathin oxide film between the Ru-containing layer and the Co-alloy magnetic recording layer. The oxide film may be an oxide selected from a Ta-oxide, a Co-oxide and a Ti-oxide, and is ultrathin so that it may be considered a discontinuous film. The planarizing layer and ultrathin oxide film improve the growth homogeneity of the Co-alloy recording layer, so that the patterned disk with data islands shows significantly reduced SFD.

摘要： An electrical circuit structure employing graphene as a charge carrier transport layer. The structure includes a plurality of graphene layers. Electrical contact is made with one of the layer of the plurality of graphene layers, so that charge carriers travel only through that one layer. By constructing the active graphene layer within or on a plurality of graphene layers, the active graphene layer maintains the necessary planarity and crystalline integrity to ensure that the high charge carrier mobility properties of the active graphene layer remain intact.

摘要： A patterned perpendicular magnetic recording disk with discrete data islands of recording layer (RL) material includes a substrate, a patterned exchange bridge layer of magnetic material between the substrate and the islands, and an optional exchange-coupling control layer (CCL) between the exchange bridge layer and the islands. The exchange bridge layer has patterned pedestals below the islands. The exchange bridge layer controls exchange interactions between the RLs in adjacent islands to compensate the dipolar fields between islands, and the pedestals concentrate the flux from the write head. The disk may include a soft underlayer (SUL) of soft magnetically permeable material on the substrate and a nonmagnetic exchange break layer (EBL) on the SUL between the SUL and the exchange bridge layer. In a thermally-assisted recording (TAR) disk a heat sink layer may be located below the exchange bridge layer and the SUL may be optional.

摘要： A Lorentz magnetoresistive sensor that employs a gating voltage to control the momentum of charge carriers in a quantum well structure. A gate electrode can be formed at the top of the sensor structure to apply a gate voltage. The application of the gate voltage reduces the momentum of the charge carriers, which makes their movement more easily altered by the presence of a magnetic field, thereby increasing the sensitivity of the sensor.

摘要： An improved structure for the construction of perpendicular recording media is disclosed. The structure includes a tri-layer IML resident between a soft under layer CoTaZr film and a CoPtCr—SiO2 magnetic media. In an embodiment, the tri-layer comprises a RuxCr1−x layer over dual nucleation layers of Ni—Fe and Ni—Fe—Cr. The tri-layer replaces the typical Ru and Ni—Fe intermediate layers of the prior art, resulting in considerable improvement in lattice matching between the Ru containing intermediate layer and the CoPtCr—SiO2 magnetic media, further resulting in improved magnetic media performance.

摘要： A perpendicular magnetic recording disk has a granular cobalt alloy recording layer (RL) containing an additive oxide or oxides, an intermediate layer (IL) as an exchange-break layer on the “soft” magnetic underlayer (SUL), and an ultrathin nucleation film (NF) between the IL and the RL. In the method of making the disk, the IL is deposited at a relatively low sputtering pressure, to thereby reduce the roughness of the RL and overcoat (OC), while the NF and RL are deposited at substantially higher sputtering pressures. The resulting disk has good recording properties and improved corrosion resistance over a comparable disk made with an IL deposited at high sputtering pressure and without the NF. The NF may be a discontinuous film with an average thickness of less than about 1 nm.
