Abstracts

EN

We discuss some aspects of the problem of spin currents in magnetic nanostructures. One of them is related to the proper definition of the spin current and is generic for any electronic or magnetic system. Using the standard method related to the symmetry with respect to local spin transformations, we analyze the generation of equilibrium spin currents in inhomogeneous magnetic structures. As an example we consider the generation of persistent spin current in a mesoscopic ring.
