摘要
A magnetic recording head includes a trailing shield and a main pole. A trailing shield gap is between the trailing shield and the main pole. A spin orbital torque structure is within the trailing shield gap. The spin orbital torque structure includes a spin torque layer having a first side and a second side at a media facing surface. A first spin Hall layer is along the first side of the spin torque layer. A second spin Hall layer is along the second side of the spin torque layer. The first spin Hall layer comprises a heavy metal material having a positive spin Hall angle. The second spin Hall layer comprises a heavy metal material having a negative spin Hall angle.
