Spin-orbit torque on nuclear spins exerted by a spin accumulation via hyperfine interactions
Adam B. Cahaya, Alejandro O. Leon, Mohammad H. Fauzi
Spin-transfer and spin-orbit torques allow controlling magnetic degrees of freedom in various materials and devices. However, while the transfer of angular momenta between electron…
Dzyaloshinskii-Moriya spin density by skew scattering
Adam B. Cahaya, Alejandro O. Leon
Anisotropic exchange couplings, such as the Dzyaloshinskii-Moriya interaction (DMI), have played a vital role in the formation and dynamics of spin textures. This work predicts an…
Voltage-control of damping constant in magnetic-insulator/topological-insulator bilayers
Takahiro Chiba, Alejandro O. Leon, Takashi Komine
The magnetic damping constant is a critical parameter for magnetization dynamics and the efficiency of memory devices and magnon transport. Therefore, its manipulation by electric…
Equilibrium current vortices in rare-earth-doped simple metals
Adam B. Cahaya, Alejandro O. Leon, Mojtaba Rahimi Aliabad +1
Dilute alloys of rare earths have played a vital role in understanding magnetic phenomena. Here, we model the ground state of dilute 4f rare-earth impurities in light metals. When…
Voltage- and temperature-dependent rare-earth dopant contribution to the interfacial magnetic anisotropy
Alejandro O. Leon, Gerrit E. W. Bauer
The control of magnetic materials and devices by voltages without electric currents holds the promise of power-saving nano-scale devices. Here we study the temperature-dependent vo…
Crystal field effects on spin pumping
Adam B. Cahaya, Alejandro O. Leon, Gerrit E. W. Bauer
"Spin pumping" is the injection of spin angular momentum by a time-dependent magnetization into an adjacent normal metal proportional to the spin mixing conductance. We study the r…
