Magnetization study of rare-earth intermetallic compounds R3Co29Si4B10

The magnetic properties of rare-earth intermetallic compounds R3Co29Si4B10 (R = La, Gd, Tb, Er, Tm) have been investigated by magnetization. All the c ompounds exhibit paramagnetism at room temperature, and magnetic ordering f rom 154 to 206 K. The magnetic moments of the Co sublattice and rare-earth sublattice couple ferrimagnetically for the heavy rare-earth compounds R3Co 29Si4B10 (R = Gd, Tb, Er, Tm). The saturation magnetic moment derived from La3Co29Si4B10 for the Co sublattice is similar to0.4 mu (B)/Co. (C) 2001 El sevier Science B.V. All rights reserved.
