In this letter, we demonstrate an apparent magnetically activated electric polarization reorientation at room temperature through magneto-electric coupling in (1 - x)BiFeO3-xPbTiO(3) (x = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5) composites. A change in magnetic field causes variation in electric polarization, attributed to the destruction of space modulated spin antiferromagnetic structure with the PbTiO3 addition. This behavior also results in the increase in magnetic parameters as the coercive field of the composites increases with the increase in PbTiO3 contents. The analysis demonstrates that the magneto-electric coupling in the prepared ferromagnetic/ferroelectric composites is dominant at room temperature, quite feasible for modern day devices.
