Magnetic field effect on dielectric properties of Pb(Fe1/2Nb1/2)O3 single crystal

Single crystal was grown by precursor flux-melt method. It was characterized by X-ray diffraction (XRD) and was found perovskite and the surface index of the crystal is (2 1 0). Scanning electron microscopic image also confirms no explicit defect on the crystal surface. The dielectric response as a function of temperature and frequency was measured in a frequency range from 100 to 106 Hz with temperatures varying from 25 to 300 °C without and with an applied magnetic field up to 14 T. The directions of applied magnetic field with respect to the direction of the applied electric field and the crystal orientation are in two configurations and three rotation angles, about the electric field direction, 0, 45, and 90°. We carefully analyzed the data and believe that the magnetic field affects on the dielectric properties of the PFN single crystal.
