Abstract
The results of ac and dc magnetic susceptibility, thermopower and Hall effect measurements of a compound Gd{sub 2}PdSi{sub 3}, establish that this compound orders magnetically below T{sub N}=20K. Though the ordering appears to be of an antiferromagnetic-type, the paramagnetic Curie temperature is positive with the magnitude being nearly the same as that of T{sub N}, suggestive of the existence of ferromagnetic correlations. The thermopower at 300K is large, apparently due to Pd 4d electrons, decreasing monotonically with temperature. There is a change in the sign of Hall constant well below T{sub N}. Also considering the observation of Kondo-like characteristics above 21 K earlier by us, the overall thermal, transport and magnetic behaviour of this compound is interesting.
