Abstract Single crystals of Pb(Fe2/3W1/3)O3 [PFW] were grown from high temp. soln. using (PbO-B2O3) flux. The crystal structure of PFW shows a B-site Fe/W disorder and a positional disorder due to at. shifts. The dielec. properties indicate relaxor ferroelec. behavior with a dispersive max. of permittivity at Tm (from 178 K at 1 kHz to 190 K at 1 MHz). A macropolar phase can be induced by application of an elec. field, leading to the induced ferroelectricity. The temp. dependence of the magnetization reveals two magnetic phase transitions at TN1 = 350 K and TN2 = 20 K, resulting from the microstructural features of the complex perovskite, characterized by B-site disordered and ordered clusters.
