摘要：

We determine the polarization vector of a spin-polarized electron beam emerging from a ferromagnet and we study the particular case of two uncoupled ferromagnetic layers with in-plane magnetizations in a perpendicular configuration. We show that the transmitted intensity depends on the three components of the primary polarization and we propose to use such a structure as a convenient spin detector for low-energy electrons.
