Abstract:
The present disclosure generally relates to magnetic media devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The recording head includes a main pole, a trailing shield hot seed layer, a spin Hall layer disposed between the main pole and the trailing shield hot seed layer, and a spin-torque layer disposed between the main pole and the trailing shield hot seed layer. Spin-orbit torque (SOT) is generated from the spin Hall layer. The spin-torque layer magnetization switching or precession is induced by the SOT. The SOT based head reduces the switching current and the V jump  due to higher spin polarization ratio, which improves energy efficiency. In addition, the spin Hall layer and the spin-torque layer are easier to form compared to the conventional pseudo spin-valve structure.

Claim (Index 16):
The data storage device of  claim 15 , wherein the spin Hall layer comprises beta phase Tantalum, beta phase tungsten, platinum, hafnium, an alloy of tungsten with hafnium, iridium, or bismuth doped copper, (Bi,Sb)Te, MnIr, XMn (X\u2550Fe, Pd, Ir, and Pt), or antiferromagnets.
