Abstract

Magnetization, frequency dependent dielectric, and structural studies on 0.73BiFeO3–0.27PbTiO3 in the temperature range from 300 to 600 K reveal anomalies in the unit cell parameters and the intrinsic value of the dielectric constant, free from space charge contributions, at the antiferromagnetic transition temperature (TN). Our results provide unambiguous confirmation of magnetoelectric coupling of multiferroic origin at TN and evidence for monoclinic distortion of the ferroelectric phase.
