Abstract
The magnetic properties of Co/V multilayers, prepared by the e-beam evaporation method, have been systematically studied by magnetic measurements. A bulk-like
T
3/2 temperature dependence of the magnetization is observed for all multilayers in the temperature range 5–300
K. A simple theoretical model based on an anisotropic ferromagnetic system has been used to explain the temperature dependence of the magnetization, and the approximate values for the in-plane exchange interaction
J
0 and the interlayer coupling strength
J
1 for various Co layer thicknesses have been obtained. The effective magnetization 4
πM
eff of Co/V multilayers is determined from the ferromagnetic resonance data. The interface contribution to the magnetic anisotropy is extracted from the anisotropy field
H
K that is obtained from 4
πM
eff.
