Abstract
We report the investigation of crystal structure, magnetic and dielectric properties of BaTi1−xFexO3 samples for x=0.0–0.3. The parent compound is found to crystallize in tetragonal structure while Fe doped samples are found to crystallize in the mixture of tetragonal and hexagonal phases but they are free from any impurity phase. Room temperature ferromagnetism with the transition temperature (Tc) of 462K was observed for x=0.3 sample. Fe doped samples exhibit ferroelectric transition with transition temperature (TcF) in the range of 390K for x=0.0–312K for x=0.2. The dielectric constant, ε′ is found to decrease with the increase in doping concentrations.
