The measurement of the direct ME effect is performed in a pulsed magnetic fields up to 35 T at liquid helium temperature for the all principal crystallographic direction as well as for the direction in which nonlinear ME effect has the maximum value. In the (AF) state the phase transition between different configurations of a spins manifested itself as plateau-like peculiarity on the nonlinear ME effect. At the same time nonlinear ME effect is saturated by the phase transition to the spin-saturated paramagnetic state. Two contributions to the nonlinear ME effects in CsCuCl3 are extracted from the experimental data: the extrinsic one, which results from a magnetostriction-induced piezoelectric effect and the intrinsic ME effect arisen from the magnetoelectric interactions.
