What is it about?
The electric polarization of the metastable orthorhombic ferroelectricferroelastic paramagnetic B' phase of Tb2(Mo04)3 was measured indirect current magnetic fields up to19T at temperatures 31-72 K. Giant internal electric fields of 105 V/cm were observed in a single domain sample of Tb2(MoO4)3.

Why is it important?
Multiple reversal of the electric polarization destroyed samples. The temperature dependence of lattice parameters of Tb2(MoO4)3 was measured at 5 K-2% K. The magnetostriction of Tb2(MoO4)3 was measured in pulsed magnetic field with pulse duration of 0.01 s up to 11 T at temperatures of 4.2 and 78 K. At 7= 78 K critical values of the field H, = 4.1 T and of the magnetostriction (AM), = 0.2 x were defined.
Perspectives
Present measurements of the electric polarization confirm previous observations of the magnetoelectric effect in Tb2(Mo04)2.
