Abstract

Abstract A quadratic magnetoelectric effet is detected in the incommensurate antiferro-magnetic phase of BaMnF4. Two of the eight third order coefficients have been determined at 4K: βxxx = 1.1 10−19 s.A−1, βxzz = -1.6 10−19 s.A−1 (relative values, not correlated with the sign of the spontaneous polarization).
