The paper reports synthesis, crystal structure, dielectric properties, P-E hysteresis loops, M-H hysteresis loops and magnetodielectric properties of Fe doped Ba 0.95 Sr 0.05 TiO 3 (0.05BST) single phase magnetodielectric compositions. The parent and doped 0.05BST compositions are synthesized via ceramic route of synthesis. The studies on crystal structure show that the parent composition (0.05BST) show a tetragonal crystal structure, while the substitution of Fe is observed to exhibit a cubic crystal structure with a tetragonal distortion. The investigations on dielectric properties show that the Fe doped 0.05BST show a diffused phase transition and T c approaches room temperature as the level of doping is increased. The studies on P-E and M-H hysteresis loops are carried out to confirm simultaneous presence of both the ferroelectric and ferromagnetic orders in a Fe doped 0.05BST. All the Fe doped compositions are found to exhibit a significant magnetodielectric coupling at room temperature.
