摘要： A method and system for providing a magnetic element and a magnetic memory utilizing the magnetic element are described. The magnetic element is used in a magnetic device that includes a contact electrically coupled to the magnetic element. The method and system include providing pinned, nonmagnetic spacer, and free layers. The free layer has an out-of-plane demagnetization energy and a perpendicular magnetic anisotropy corresponding to a perpendicular anisotropy energy that is less than the out-of-plane demagnetization energy. The nonmagnetic spacer layer is between the pinned and free layers. The method and system also include providing a perpendicular capping layer adjoining the free layer and the contact. The perpendicular capping layer induces at least part of the perpendicular magnetic anisotropy in the free layer. The magnetic element is configured to allow the free layer to be switched between magnetic states when a write current is passed through the magnetic element.

摘要： A magnetic junction is provided. The magnetic junction includes a reference stack, a nonmagnetic spacer layer and a free layer. The reference stack includes a high perpendicular magnetic anisotropy (PMA) layer and a graded polarization enhancement layer (PEL) between the high PMA and nonmagnetic spacer layers. The PEL is magnetically coupled with the reference layer. The PEL includes magnetic layers and nonmagnetic insertion layers. At least part of the PEL has a spin polarization greater than the PMA layer's. The nonmagnetic insertion layers are configured such that the magnetic layers are ferromagnetically coupled and the crystalline orientations of the high PMA and nonmagnetic spacer layers are decoupled. Each nonmagnetic insertion layer's thickness is insufficient for the crystalline orientations to be decoupled in the absence of the remaining nonmagnetic insertion layers. The free layer is switchable between stable magnetic states when a write current is passed through the magnetic junction.

摘要： A patterned disk for a hard disk drive. The patterned disk includes a magnetic material over a substrate. The magnetic material includes a plurality of grooves. The grooves are filled with a lubricant that is hardened with UV exposure or some other hardening process. The lubricant provides a protective cover for the magnetic material exposed by the grooves. The use of lubricants in the fabrication of disks is known, thus the process does not introduce a process step that requires special equipment and/or process development.

摘要： A patterned disk for a hard disk drive. The patterned disk includes an anti-ferromagnetic layer of FexNi1-xO over a substrate. The disk also includes a magnetic layer that is adjacent to the anti-ferromagnetic layer of FexNi1-xO, and is formed into a plurality of dots separated by a non-magnetic material. The anti-ferromagnetic layer of FexNi1-xO with the magnetic layer create an exchange-spring system that has a relatively low switching field. The anti-ferromagnetic layer of FexNi1-xO has a Neel temperature that maintains thermal stability. The low switching field improves reliability when the disk is a bit pattern media used in perpendicular recording.

摘要： A hard disk drive that includes a head coupled to a disk. The head has a heater element. The drive also includes a controller that causes the heater element to heat the head to a temperature sufficient to anneal material within the head. The head is heated to a temperature sufficient to cause oxidation of any metal, such as aluminum, within the head, and/or oxygen redistribution and homogenization in the barrier. This heating process preferably occurs while the drive is not writing or reading data and the head is off disk.
