What are spin currents in Heisenberg magnets?
Florian Schuetz, Peter Kopietz, Marcus Kollar
We discuss the proper definition of the spin current operator in Heisenberg magnets subject to inhomogeneous magnetic fields. We argue that only the component of the naive "current…

Persistent spin currents in mesoscopic Heisenberg rings
Florian Schuetz, Marcus Kollar, Peter Kopietz
We show that at low temperatures T an inhomogeneous radial magnetic field with magnitude B gives rise to a persistent magnetization current around a mesoscopic ferromagnetic Heisen…
