摘要：
An experimental study is reported of the nonlinear magnetoelectric effect in the metastable orthorhombic ferroelectric ferroelastic paramagnetic beta(') phase of Gd-2(MoO4)(3) in magnetic fields of up to 20 T and at temperatures of 4.2 and 0.4 K. It is shown that the present models of the paramagnetoelectric effect can be reconciled with experiments only for low magnetic fields. A new approach to the description of the magnetoelectric effect in rare-earth molybdates is proposed, which is based on a model of single-ion magnetostriction. (C) 2000 MAIK "Nauka/Interperiodica".
