Oscillatory spin-orbit torque switching induced by field-like torques
Jong Min Lee, Jae Hyun Kwon, Rajagopalan Ramaswamy +7
Deterministic magnetization switching using spin-orbit torque (SOT) has recently emerged as an efficient means to electrically control the magnetic state of ultrathin magnets. The…
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…
Interfacial Rashba magnetoresistance of two-dimensional electron gas at LaAlO/SrTiO interface
Kulothungasagaran Narayanapillai, Gyungchoon Go, Rajagopalan Ramaswamy +6
We report the angular dependence of magnetoresistance in two-dimensional electron gas at LaAlO/SrTiO interface. We find that this interfacial magnetoresistance exhibits a s…
