Abstract
The initial ac-susceptibility and the Curie temperature T-C of amorphous R(x)Co(70-x)B(30) alloys (R = Y, Tm; x = 2, 4, 6, 8) have been investigated under high hydrostatic pressure up to 9 kbar over 3. wide temperature range from 80 to 500 K. A small decrease in T-C was observed under pressure for all the R(x)Co(70-x)B(30) alloys studied. The value of the pressure parameter dT(C)/d(p) decreases monotonically from -0.1 to -0.6 K/kbar with increasing content of the R element and decreasing T-C. Using the theoretical band models of magnetism, the studied R(x)Co(70-x)B(30) alloys can be characterised as homogeneous strong itinerant ferromagnets.
