Persistent Spin Currents in Helimagnets
arXiv:cond-mat/0305069 · doi:10.1103/PhysRevB.68.064406
Abstract
We demonstrate that weak external magnetic fields generate dissipationless spin currents in the ground state of systems with spiral magnetic order. Our conclusions are based on phenomenological considerations and on microscopic mean-field theory calculations for an illustrative toy model. We speculate on possible applications of this effect in spintronic devices.
