Accurate analysis for harmonic Hall voltage measurement for spin-orbit torques
Seok Jin Yun, Eun-Sang Park, Kyung-Jin Lee +1
An accurate method is developed to extract the spin-orbit effective fields through analysis of the results of harmonic Hall voltage measurements by deriving detailed analytical equ…
Spin-wave propagation in the presence of inhomogeneous Dzyaloshinskii-Moriya interactions
Seung-Jae Lee, Jung-Hwan Moon, Hyun-Woo Lee +1
We theoretically investigate spin-wave propagation through a magnetic metamaterial with spatially modulated Dzyaloshinskii-Moriya interaction. We establish an effective Sch{ö}dinge…
Anomalous spin-orbit torque switching due to field-like torque-assisted domain wall reflection
Jungbum Yoon, Seo-Won Lee, Jae Hyun Kwon +5
Spin-orbit torques (SOT) allow the electrical control of magnetic states. Current-induced SOT switching of the perpendicular magnetization is of particular technological importance…
Dzyaloshinskii-Moriya interaction induced extrinsic linewidth broadening of ferromagnetic resonance
Jung Hyun Oh, Ik-Sun Hong, Kyung-Jin Lee
For a thin ferromagnetic film with the Dzyaloshinskii-Moriya interaction (DMI), we derive an expression of the extrinsic ferromagnetic resonance (FMR) linewidth in a quantum mechan…
Observation of transverse spin Nernst magnetoresistance induced by thermal spin current in ferromagnet/non-magnet bilayers
Dong-Jun Kim, Chul-Yeon Jeon, Jong-Guk Choi +5
Electric generation of spin current via spin Hall effect is of great interest as it allows an efficient manipulation of magnetization in spintronic devices. Theoretically, spin cur…
Perovskite ThTaN3: a Large Thermopower Topological Crystalline Insulator
Myung-Chul Jung, K. -W. Lee, W. E. Pickett
ThTaN, a rare cubic perovskite nitride semiconductor, has been studied using {\it ab initio} methods. Spin-orbit coupling (SOC) results in band inversion and a band gap of 150…
