A high-temperature multiferroic Tb2(MoO4)3 — •Shimon Tajima, Hidetoshi Masuda, Yoichi Nii, Shojiro Kimura, and Yoshinori Onose — Institute for Materials Research, Tohoku University, Sendai, Japan
We demonstrated magnetic control of ferroelectric polarization at 432 K in ferroelectric and ferroelastic Tb2(MoO4)3, in which the polarity of ferroelectric polarization is coupled to the orthorhombic strain below the transition temperature 432 K.
The paramagnetic but strongly magnetoelastic Tb3+ magnetic moments enable the magnetic control of ferroelectric and ferroelastic domains; the ferroelectric polarization is controlled depending on whether the magnetic field is applied along [110] or [110].
