Vertically Graded Fe-Ni Alloys with Low Damping and a Sizeable Spin-Orbit Torque
Rachel E. Maizel, Shuang Wu, Purnima P. Balakrishnan +13
Energy-efficient spintronic devices require a large spin-orbit torque (SOT) and low damping to excite magnetic precession. In conventional devices with heavy-metal/ferromagnet bila…
