Abstract: A spin torque oscillation generator includes a spin reference layer and a spin oscillation layer. The spin reference layer has a first magnetization direction. The spin reference layer is configured to receive a current and generate a spin-polarized current. The spin oscillation layer has a second magnetization direction. The second magnetization direction is different than the first magnetization direction. The spin oscillation layer is configured to receive the spin-polarized current from the spin reference layer. The spin-polarized current generates a spin torque based on the second magnetization direction of the spin oscillation layer. The spin torque generates a spin torque output signal.

Abstract: An apparatus includes a substrate and a magnetic layer coupled to the substrate. The magnetic layer includes an alloy that has magnetic hardness that is a function of the degree of chemical ordering of the alloy. The degree of chemical ordering of the alloy in a first portion of the magnetic layer is greater than the degree of chemical ordering of the alloy in a second portion of the magnetic layer, and the first portion of the magnetic layer is closer to the substrate than the second portion of the magnetic layer.

Abstract: Aspects include recording media with enhanced areal density through reduction of head media spacing, head keeper spacing, or head to soft underlayer spacing. Such aspects comprise replacing currently non-magnetic components of devices, such as interlayers and overcoats with components and compositions comprising magnetic materials. Other aspects relate to magnetic seed layers deposited within a recording medium. Preferably, these aspects, embodied as methods, systems and/or components thereof reduce effective magnetic spacing without sacrificing physical spacing.
