Magnetoelectric Study In Terfenol-D/Tb-2(Moo4)(3) Bilayer Composite

The dependence of the magnetoelectric coefficients (alpha(E)) in the Terfenol-D/Tb-2(MoO4)(3) bilayer composite on the magnetic bias fields and the frequencies has been studied. The strain with butterfly loop of Tb-2(MoO4)(3) under an external magnetic field was observed and the effect of ferroelasticity of the Tb-2(MoO4)(3) on the magnetoelectric coupling was discussed. More than one peak of alpha(E) as function of frequency of ac magnetic field were observed and it implies existence of bending resonance mode besides the longitudinal resonance mode in the bilayer composite.
