Abstract

Co-Nb(3.6 nm)/Pd(d(Pd) nm) multilayers were prepared by the rf sputtering method. The polarization of Pd layers and the interlayer couplingthrough Pd layers were studied via magnetic and ferromagnetic resonance measurements. Magnetic measurement shows that the saturation magnetization of Co-Nb/Pd multilayers oscillates periodically when the Pd layer thickness increases, which is caused by the oscillatory polarization of the Pd layers. The spin-wave excitation indicates that a ferromagnetic interlayer coupling can exist until the thickness of the Pd layers is about 7 nm An oscillatory variation between 2.00 and 2.12 of the effective g-factor, g(eff), with the thickness of Pd layers was observed for the first time. The oscillatory period of g(eff) is about 1 nm. A similar oscillatory behaviour of the effective anisotropy, K-e, was also obtained. This oscillatory behaviour of g(eff) and K-e was interpreted in terms of a model of two exchange-coupled sublattices: one sublattice is that of the Co-Nb magnetic layers, and the other is thatof the polarized Pd layers. This model indicates that the oscillatorybehaviour of g(eff) and K-e mainly originates from the oscillation ofthe polarization of the Pd layers.
