Abstract:
Methods, devices, and compositions for use with spintronic devices such as magnetic random access memory (MRAM) and spin-logic devices are provided. Methods include manipulating magnetization states in spintronic devices and making a structure using spin transfer torque to induce magnetization reversal. A device described herein manipulates magnetization states in spintronic devices and includes a non-magnetic metal to generate spin current based on the giant spin Hall effect, a ferromagnetic thin film with perpendicular magnetic anisotropy, an oxide thin film, and an integrated magnetic sensor. The device does not require an insertion layer between a non-magnetic metal with giant spin Hall effect and a ferromagnetic thin film to achieve perpendicular magnetic anisotropy.
