Abstract

We study the spin-dependent conductance of ballistic mesoscopic ring systems in the presence of an inhomogeneous magnetic field. We show that, for the set-up proposed, even a small Zeeman splitting can lead to a considerable spin polarization of the current. Making use of a spin- switch effect (Frustaglia {\it et al} 2001 {\it Phys. Rev. Lett.} {\bf 87} 256602) we propose a device of two ...
