Abstract
Single step solid state reaction method was adopted to synthesize 0.9PFN - 0.1BFO (PFN - BFO) multiferroic solid solution. Single phase was confirmed through X-Ray Diffraction (XRD) and the structural analysis from Rietveld refinement confirms the monoclinic structure with Cm space group. Temperature dependent dielectric constant and loss tangent shows an anomaly around Néel temperature (TN) at 240 K and is a clear signature of existence of indirect magnetoelectric coupling in the solid solution. The complex impedance spectroscopy exhibits a significant contribution from the grains and confirms the non Debye type nature. Bulk resistance decreases with increase in temperature shows negative temperature coefficient of resistance (NTCR) behavior. Electrical modulus spectra are of non Debye type. The ac and dc conductivity of the materials were found to increase with increase in temperature.
