Thermal effects on the magnetic-field dependence of spin-transfer-induced magnetization reversal
Thermal effects on the magnetic-field dependence of spin-transfer-induced magnetization reversal
We have developed a self-aligned, high-yield process to fabricate current-perpendicular-to-plane giant magnetoresistance (GMR) spin-valve sensors of sub-100-nm dimensions. A pinned synthetic antiferromagnet is used as the reference layer which minimizes dipole coupling to the free layer and field-induced rotation of the reference layer. We find that the critical currents for …
