Abstract
The magnetic properties of sputtered Ni/V multilayers have been studied in a vibrating sample magnetometer, torque magnetometer and by ferromagnetic resonance (FMR). The magnetization decreases with decreasing Ni layer thickness, which is an indication of the structural imperfections at interface. The interface contribution to the magnetic anisotropy is practically negligible. The spin-waves resonance modes were observed for perpendicular geometry, which implied that spin waves were sustained by the whole film and propagated through V layers in some Ni/V multilayers. The relation of the resonance field Hn with the mode number n obeys the so-called n2 law and the interlayer exchange constants were determined.
