Abstract:

In order to investigate the difference between the electronic structures of the ferrimagnetic and antiferromagnetic states in Mn2-xCrxSb compounds the specific heat has been measured for Mn2Sb and Mn1.9Cr0.1Sb which have ferrimagnetic (FR) and antiferromagnetic (AF) structures respectively at low temperatures. This revealed a great difference between the electronic specific heat coefficients gamma for these two compounds: gamma(FR) = 1.4 mJ mol-1 K-2 and gamma(AF)= 20.9 mJ mol-1 K-2. This difference allows us to suggest that the AF-FR magnetic transition in Mn2-xCrxSb is caused by the peculiarities of electronic structure and the band magnetism model is necessary to explain the magnetic properties of these compounds.
