The magnetization of the pseudo-binary intermetallic compounds (Dy x Y 1− x )Fe 2 and (Er x Y 1− x )Fe 2 was studied in high magnetic fields (up to 20 T). The saturation magnetization shows a minimum as a function of concentration, due to the anti-parallel coupling of the R and Fe moments. From the magnetization curve in the high field region we derived the spontaneous magnetization and high field susceptibility, as a function of concentration. The susceptibilities, coercive fields and the anisotropy terms show maxima in the 20−40% concentration range. |
