Room Temperature Giant Charge-to-Spin Conversion at SrTiO3/LaAlO3 Oxide Interface
Yi Wang, Rajagopalan Ramaswamy, M. Motapothula +5
Two-dimensional electron gas (2DEG) formed at the interface between SrTiO3 (STO) and LaAlO3 (LAO) insulating layer is supposed to possess strong Rashba spin-orbit coupling. To date…
Room temperature magnetization switching in topological insulator-ferromagnet heterostructures by spin-orbit torques
Yi Wang, Dapeng Zhu, Yang Wu +9
Topological insulators (TIs) with spin momentum locked topological surface states (TSS) are expected to exhibit a giant spin-orbit torque (SOT) in the TI/ferromagnet systems. To da…
Experimental study of extrinsic spin Hall effect in CuPt alloy
Rajagopalan Ramaswamy, Yi Wang, Mehrdad Elyasi +4
We have experimentally studied the effects on the spin Hall angle due to systematic addition of Pt into the light metal Cu. We perform spin torque ferromagnetic resonance measureme…
