[en] In our theoretical work we found a new type of spin polarization and current oscillations in conducting rings with inhomogeneous magnetic properties. We assume that the effective magnetic field magnitude in conductor is a function of coordinate but in all the bulk magnetization is collinear. In this case the electronic system can be described by macroscopic variables: the spin density and spin current for each spin band (common two-current model). These new spin oscillations in closed conductors can be used in spintronic devices like the well known LC circuit used in radio electronics. It can be also used as 'atoms' of novel metamaterials.
