Spin-orbit torque induced magnetization switching in a magnetic recording head

A magnetic recording head, comprising:

• a trailing shield hot seed layer;
• a leading shield;
• a main pole, wherein the main pole includes a first surface at a media facing surface, a second surface facing the trailing shield hot seed layer, a third surface opposite the second surface, a fourth surface connecting the second surface and the third surface, and a fifth surface opposite the fourth surface;
• a spin Hall structure recessed from the media facing surface, wherein the spin Hall structure surrounds at least three surfaces of the second, third, fourth and fifth surfaces of the main pole;
• and
• a spin-torque structure coupled to the spin Hall structure, wherein the spin-torque structure surrounds at least three surfaces of the second, third, fourth and fifth surfaces of the main pole at the media facing surface.

A data storage device, comprising:

• a magnetic recording head, comprising:
• 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, wherein the spin Hall layer is recessed from a media facing surface;
• and
• a spin-torque layer disposed between the main pole and the trailing shield hot seed layer, wherein the spin-torque layer includes a surface at the media facing surface.
