Abstract

Neutron diffraction, magnetic susceptibility, specific heat, and dielectric constant measurements of single crystal Co₃TeO₆ have been measured to study the interplay between the ferroelectricy and magnetic order. Long range incommensurate magnetic order develops below T_ń1=26 K, which is followed by three additional zero-field phase transitions at T_ń2=19.5 K, T_ń3=18 K, and T_ń4 = 16 K where the incommensurate order changes and commensurate order develops. In magnetic fields up to 14 T we find that the magnetic intensities and incommensurate wave vector are dramatically altered as ferroelectricity develops, with a fifth abrupt transition around 10 T. The overall behavior characterizes Co₃TeO₆ as a type-II Multiferroic.
