Spin-orbit torques and spin Hall magnetoresistance generated by twin-free and amorphous Bi0.9Sb0.1 topological insulator films
Federico Binda, Stefano Fedel, Santos Francisco Alvarado +2
Topological insulators have attracted great interest as generators of spin-orbit torques (SOTs) in spintronic devices. Bi\textsubscript{1-x}Sb\textsubscript{x} is a prominent topol…
Localized Magnetic States of Fe, Co, and Ni Impurities on Alkali Metal Films
P. Gambardella, S. S. Dhesi, Sandra Gardonio +3
X-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD) have been used to study transition metal impurities on K and Na films. The multiplet structure of t…
Field-Free Spin-Orbit Torque driven Switching of Perpendicular Magnetic Tunnel Junction through Bending Current
Vaishnavi Kateel, Viola Krizakova, Siddharth Rao +10
Current-induced spin-orbit torques (SOTs) enable fast and efficient manipulation of the magnetic state of magnetic tunnel junctions (MTJs), making it attractive for memory, in-memo…
Electrically programmable magnetic coupling in an Ising network exploiting solid-state ionic gating
Chao Yun, Zhongyu Liang, Aleš Hrabec +12
Two-dimensional arrays of magnetically coupled nanomagnets provide a mesoscopic platform for exploring collective phenomena as well as realizing a broad range of spintronic devices…
Strong lateral exchange coupling and current-induced switching in single-layer ferrimagnetic films with patterned compensation temperature
Zhentao Liu, Zhaochu Luo, Ivan Shorubalko +4
Strong, adjustable magnetic couplings are of great importance to all devices based on magnetic materials. Controlling the coupling between adjacent regions of a single magnetic lay…
Current-driven dynamics and ratchet effect of skyrmion bubbles in a ferrimagnetic insulator
Saül Vélez, Sandra Ruiz-Gómez, Jakob Schaab +8
Magnetic skyrmions are compact chiral spin textures that exhibit a rich variety of topological phenomena and hold potential for developing high-density memory devices and novel com…
