Abstract:

Measurements of the specific heat have been performed on Gd1-xYxNi2 (x=0,0.2) compounds and their nonmagnetic analogs Lu1-yYyNi2, which have similar molar masses. It is found that the difference between the entropies of magnetic and nonmagnetic compounds with identical molar masses surpasses substantially (by 14-19\%) the theoretical limit for the magnetic contribution S-m=(1-x)R ln(8) calculated assuming that only Gd ions possess a magnetic moment. This observed enhancement of the magnetic entropy in Gd1-xYxNi2 is believed to result from spin fluctuations induced by f-d exchange in the 3d electron subsystem of Ni.
