Phase transitions, magnetic and dielectric properties of PbFe0.5Nb0.5O3

Ferroelectrics (2016)

К. Г. Абдулвахидов Elza Ubushaeva I. V. Mardasova M. A. Vitchenko Bashir Abdulvakhidov

ABSTRACTIn this paper the investigation of relaxor ferroelectric PbFe0.5Nb0.5O3 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 χ (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.

The influence of the stress‐induced structural defects in PbZrO 3 on its structural, optical, and dielectric properties is studied systematically for the first time. The PbZrO 3 ceramics is prepared by a conventional solid state synthesis. The structural defects in PbZrO 3 are generated by the combined action of mechanical compression due to applied pressure in the 40–320 MPa range and the shear strain appearing in the rotating Bridgman anvils. The pressure dependencies of the cell parameters, the mean size of coherent scattering regions and the microstrain, the Debye characteristic temperature, and the isotropic Debye–Waller factor are calculated from processing the X‐ray diffraction (XRD) data and commented on. The local structure around Pb and Zr atoms is probed with the X‐ray absorption near edge structure (XANES). This approach demonstrates the possibility of controlling the dielectric, electronic, and structural parameters of PbZrO 3 by changing the concentration of the stress‐induced structural defects.
