Abstract

A giant magnetoelectric polarization is found in HoAl₃(BO ₃)₄. The polarization in transverse field geometry at 70 kOe reaches 3600 μ?C/m2, which is significantly higher than reported values of linear magnetoelectric or even multiferroic compounds. The magnetostrictive effect is also measured and compared with the magnetoelectricity. The results show that spin-lattice coupling in HoAl₃(BO₃)₄ is extremely strong and that the magnetic field causes a large polar distortion of the ionic positions in the unit cell.
