摘要
The magnetic behavior of evaporated Co/Nb multilayers has been investigated by magnetic measurements and ferromagnetic resonance (FMR). The modes of spin-wave (S-W) resonances were observed in some Co/Nb multilayers in FMR measurements. So, the S-Ws were sustained by the whole layers and propagated through the Nb layers. The dependence of the mode number n on the resonance field H-res is following the n(2) law. As a result, the interlayer coupling constant (J(I)) was determined. A S-W theory has been applied to explain the variation of the magnetization versus temperature and hence to estimate the approximate values of the bulk exchange interaction (J(b)) and interface exchange interaction (J(int)) for various Co/Nb multilayers.
