Abstract

Bismuth calcium ferric titanate Bi(Ca0.25Ti0.25Fe0.5)O3 compound is synthesized via solid state reaction route. Using different experimental procedures, the specimen has been characterized. Investigation regarding crystal system with the help of X-ray diffraction (XRD) data suggests the rhombohedral system. Detailed investigations of dielectric and electrical properties of Bi(Ca0.25Ti 0.25Fe0.5)O3 in a broad frequency (1 kHz–1 MHz) and temperature (25–500 °C) ranges have offered a variety of exciting outcomes of conduction mechanism, structure and correlation properties, etc. A significant role of interface in obtaining good dielectric compound has been noticed. The existence of polarization (PE) hysteresis loop indicates the existence of ferroelectricity in the material. The existences of Maxwell–Wagner dielectric relaxation and space charge polarization at low frequencies and high temperatures in the material have been realized. The Nyquist graphs confer the temperature-dependent assistance of grain and grain boundary effect. The transport properties and ac conductivity of the material, which are affected by the temperature and frequency of the applied electric field, have been studied. It exhibits semiconductor behavior. The magneto-electric coupling coefficient of the examined specimen is found to be 3.8 mV cm− 1Oe− 1 at zero magnetic field.
