Abstract

Magnetic properties of multilayered Co/Cr films have been investigated by ferromagnetic resonance (FMR) and compared to magnetization studies carried out on a SQUID magnetometer. The interesting feature observed in most of the spectra was that along with an intense resonance corresponding to the uniform mode, several weak but well-defined peaks were observed at higher magnetic fields. The angular and temperature variations of the line positions indicates that these are due to cobalt atoms in the interface. In conjunction with static magnetization, the FMR studies of the main resonance lead us to believe that there may be long-range magnetic effects which result in additional anisotropy fields.
