Description
Summary:	In this paper the investigation of relaxor ferroelectric PbFe sub(0.5)Nb sub(0.5)O sub(3) has been carried out using the method of X-ray diffraction, magnetic and dielectric measurements over a wide range of temperatures and frequencies. It has been shown that in single crystals there is high-temperature phase transition from the ferroelectric phase to the cubic phase at a temperature of 367 K. The anomalies detected in the dependences of magnetic susceptibility chi (T) and the magnetic moment m (T) in polycrystalline at room temperature and above were found to be correlating with the anomalies detected by structural, EPR spectroscopic and dielectric measurements.
