Abstract

Magnetic and ferroelectric materials are time-honored subjects to study which led to some of the most important technological advances such as data storage devices, filtering devices, actuators and high performance insulators. The materials which exhibit coupling between two ordered parameters, i.e., spin and charge are called multiferroic materials. BiFeO3-PbTiO3 is alsoone of the extensively studied multiferroic binary system in recent times.In the present report we have also studied the Sr modified BiFeO3-PbTiO3. The conventional solid state reaction technique is employed to prepare (1-x)BiFeO3-x(Pb0.90Sr0.10)TiO3 with x = 0.2 and 0.3. The Rietveld refinement studies show the existence of morphotropic phase boundary between rhombohedral (R3c) and tetragonal (P4mm) phases for x = 0.3 and rhombohedral (R3c) phase for x = 0.2. The polarization-electric field loops reveal that the ferroelectricity is compositional dependent. Magnetic field dependent magnetization measurements show the antiferromagnetic behavior with weak ferromagnetic nature.
