Abstract:

The results of specific heat, magnetization and magnetic susceptibility measurements for the antiferromagnetic (AF) compound Gd3Rh are presented. Below its Neel temperature T-N = 112 K, this compound exhibits a field-induced phase transition from the AF to the ferromagnetic state in a relatively small magnetic field (similar to0.4 T). Specific heat measurements revealed giant enhancement of the coefficient of the T-linear specific heat in Gd3Rh (gamma = 118 mJ mol(-1) K-2) in comparison with that observed for the isostructural nonmagnetic partner Y3Rh (gamma = 11 mJ mol(-1) K-2). An anomalous behaviour of the heat capacity as well as a set of peculiarities of magnetic properties in Gd3Rh are associated with the existence of spin fluctuations induced by f-d exchange interaction in the d-electron subsystem that arises from features of the crystal and electronic structure of-the R3M-type compounds.
