Abstract:
A spin transfer torque (STT) device has a free ferromagnetic layer that includes a Heusler alloy layer and a template layer beneath and in contact with the Heusler alloy layer. The template layer may be a ferromagnetic alloy comprising one or more of Co, Ni and Fe and the element X, where X is selected from one or more of Ta, B, Hf, Zr, W, Nb and Mo. A CoFe nanolayer may be formed below and in contact with the template layer. The STT device may be a spin-torque oscillator (STO), like a STO incorporated into the write head of a magnetic recording disk drive. The STT device may also be a STT in-plane or perpendicular magnetic tunnel junction (MTJ) cell for magnetic random access memory (MRAM). The template layer reduces the critical current density of the STT device.

Claim (Index 1):
A spin transfer torque (STT) device comprising:\n a substrate; and a stack of layers formed on the substrate and comprising:\n a free layer comprising a ferromagnetic Heusler alloy layer and a template layer located beneath and in contact with said Heusler alloy layer, \n a ferromagnetic polarizing layer, and \n a nonmagnetic spacer layer between the free layer and the polarizing layer, \n wherein said Heusler alloy layer is selected from the group consisting of Co2MnX (where X is selected from the group consisting of Al, Sb, Si, Sn, Ga, and Ge), Co2FeZ (where Z is selected from one or more of Ge, Si, Al, Sn or Ga), NiMnSb and PtMnSb, and wherein said template layer comprises an alloy comprising one or more of Co, Ni and Fe and the element X, where X is selected from one or more of Ta, B, Hf, Zr, W, Nb and Mo.
