Abstract :
A systematic study of the effect of substitution of Cu in MM[Co1-xCux]5 0 \\leq x \\leq 1 and Fe in[MM Co1-xFex]5 0 \\leq x \\leq 0.3 were made. The Cu substitution for Co gives stable CaCu5type phase in the entire composition range. The lattice parameters \\underline {a} and \\underline {c} of the 1:5 phase increase linearly with increasing Cu content. Fe has only a limited solid solubility in the 1:5 phase. For MM[Co1-xCux]5alloys the 4\\pi M_{s} decreased from 95 e.m.u. g-1at x=0 to about 3 e.m.u. g-1at x=1 while for MM[Co1-xFex]5alloys it increased to 101 e.m.u. g-1at x=0.1 . A detailed phase composition of the alloys at 900°C and 700°C and the effect of Cu on the Tcof the 1:5 phase are also reported.
