Magnetization, frequency dependent dielectric, and structural studies on 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 . Our results provide unambiguous confirmation of magnetoelectric coupling of multiferroic origin at and evidence for monoclinic distortion of the ferroelectric phase.
