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.
