signal of the optical ME effect (Δ α t∼ 3× 10-3) is observed with an applied magnetic field as
low as 500 Oe and a sample thickness (t) of 50 μ m. The observation of a large ME effect in

The optical magnetoelectric (ME) effect, i.e., the change of optical absorption upon the reversal of the light propagation direction, has been investigated for a polar ferrimagnet . For dipole- and spin-forbidden transition bands located at 1.2–2.3 eV, a clear signal of the optical ME effect () is observed with an applied magnetic field as low as 500 Oe and a sample thickness () of . The observation of a large ME effect in the present compound suggests a possible route to magnification of this novel phenomenon for application.
