Abstract

The influence of the annealing effect on the magnetic polarization and FMR linewidth of the amorphous alloys Co/sub 10/Pd/sub 70/Si/sub 20/ and Co/sub 13/Pd/sub 67/Si/sub 20/ was studied at room temperature. A small maximum of the polarization was observed at the annealing temperature ta/spl sim/400/spl deg/C, which corresponds to the region of the crystallization. The values of the saturation magnetic polarization from magnetometric measurements were compared with the effective value obtained from FMR. This suggests that the maximum volume of Co clusters occurs for the materials annealed at t/sub aspl sim/700-800/spl deg/C. The possible contribution of magnetic inhomogeneities to the linewidth is discussed.<>
