Intrinsic Dynamic Generation of Spin Polarization by Time-Varying Electric Field
arXiv:2409.09669 · doi:10.1103/7blz-pswv
Abstract
Electric control of spin in insulators is desired for low-consumption and ultrafast spintronics, but the underlying mechanism remains largely unexplored. Here, we propose an intrinsic effect of dynamic spin generation driven by time-varying electric field. In the intraband response regime, it can be nicely formulated as a Berry curvature effect and leads to two phenomena that are forbidden in the limit: linear spin generation in nonmagnetic insulators and intrinsic N{é}el spin-orbit torque in -symmetric antiferromagnetic insulators. These phenomena are driven by the time derivative of field rather than the field itself, and have a quantum origin in the first-order dynamic anomalous spin polarizability. Combined with first-principles calculations, we predict sizable effects driven by terahertz field in nonmagnetic monolayer Bi and in antiferromagnetic even-layer MnBiTe, which can be detected in experiment.
