Both superparaelectric and superparamagnetic behaviour has been observed in rare earth magnetic ion Gd{sup 3+} doped Lead Magnesium Niobate (Gd-PMN). Field induced polarization and magnetization studies reveal hystresis loss free P-E and M-H loop at 300 K and 5 K, respectively. Temperature dependence of inverse susceptibility plot shows deviation at a temperature “t{sub d}” when fitted with the Curie-Weiss law. This deviation has been attributed to transition from paramagnetic to superparamagnetic behaviour as reported in amorphous Pd-Ni-Fe-P alloys.
