Abstract:

Mn2Sb is a ferrimagnet, and substitution of Co or Cr for Mn above the critical concentration results in the appearance of a spontaneous first-order magnetic phase transition from ferrimagnetic (FRI) to antiferromagnetic (AF) with decreasing temperature below T-t. At T < T-t a first-order field-induced AF-FRI transition is observed at a critical field B,. The spontaneous as well as the field induced AF-FRI transition is accompanied by a significant magnetovolume effect. Magnetization under high pressure up to 12 kbar, magnetostriction of Mn1.8Co0.2Sb and Mn1.94Cr0.04Sb as well as thermal expansion of the Mn1-xCoxSb system has been measured in order to clarify the origin of the contradictory experimental results on the pressure effect on B-c and that on T-t implying opposite changes. The observed differences are explained by the found anomalous change of sign of the magnetovolume effect at the AF-FRI transition with decreasing temperature. (C) 2004 Elsevier B.V.
