Claim 10:
11. A magnetic recording head, comprising:
a main pole;
a spintronic device disposed on the main pole, the spintronic device comprising:
a spin torque layer;
a Cu layer disposed over the spin torque layer; and
a spin transparent texture layer disposed on the Cu layer, the spin transparent texture layer comprising AgSn or AgZn; and

a trailing shield disposed on the spintronic device, the trailing shield comprising:
a CoFe layer disposed over the spin transparent texture layer; and
