Topological Hall effect at above room temperature in heterostructures composed of a magnetic insulator and a heavy metal
Qiming Shao, Yawen Liu, Guoqiang Yu +7
Non-volatile memory and computing technology rely on efficient read and write of ultra-tiny information carriers that do not wear out. Magnetic skyrmions are emerging as a potentia…
Exploring interfacial exchange coupling and sublattice effect in heavy metal/ferrimagnetic insulator heterostructures using Hall measurements, x-ray magnetic circular dichroism, and neutron reflectometry
Qiming Shao, Alexander Grutter, Yawen Liu +13
We use temperature-dependent Hall measurements to identify contributions of spin Hall, magnetic proximity, and sublattice effects to the anomalous Hall signal in heavy metal/ferrim…
Dirac-Surface-State Modulated Spin Dynamics in a Ferrimagnetic Insulator at Room Temperature
Chi Tang, Qi Song, Cui-Zu Chang +10
This work demonstrates dramatically modified spin dynamics of magnetic insulator (MI) by the spin-momentum locked Dirac surface states of the adjacent topological insulator (TI) wh…
Pressure-induced spin reorientation transition in layered ferromagnetic insulator Cr2Ge2Te6
Zhisheng Lin, Mark Lohmann, Zulfikhar A. Ali +9
Anisotropic magnetoresistance (AMR) of Cr2Ge2Te6 (CGT), a layered ferromagnetic insulator, is investigated under an applied hydrostatic pressure up to 2 GPa. The easy axis directio…
Above 400 K Robust Perpendicular Ferromagnetic Phase in a Topological Insulator
Chi Tang, Cui-Zu Chang, Gejian Zhao +8
The quantum anomalous Hall effect (QAHE) that emerges under broken time-reversal symmetry in topological insulators (TI) exhibits many fascinating physical properties for potential…
Deficiency of the Bulk Spin Hall Effect Model for Spin-Orbit Torques in Magnetic Insulator/Heavy Metal Heterostructures
Junxue Li, Guoqiang Yu, Chi Tang +9
Electrical currents in a magnetic insulator/heavy metal heterostructure can induce two simultaneous effects, namely, spin Hall magnetoresistance (SMR) on the heavy metal side and s…
