Spin polarization of nonmagnetic layers in multilayers

Abstract Magnetic measurements, ferromagnetic resonance, magneto-optical Kerr rotation and nuclear magnetic resonance have been used to study the spin polarization of nonmagnetic layers of Pd, Cu, Ag and Al in multilayers and sandwiches containing Fe, Co, FeCo and CoCr. The existence of the spin polarization of Pd, Cu, Ag and Al was demonstrated directly or indirectly.
