Abstract

We report on the growth of multiferroic Yb₂CoMnO₆ and Lu₂CoMnO₆ single crystals which were synthesized by the flux method with Bi₂O₃. Yb₂CoMnO₆ and Lu₂CoMnO₆ crystallize in a double-perovskite structure with a monoclinic P2₁/n space group. Bulk magnetization measurements of both specimens revealed strong magnetic anisotropy and metamagnetic transitions. We observed a dielectric anomaly perpendicular to the c axis. The strongly coupled magnetic and dielectric states resulted in the variation of both the dielectric constant and the magnetization by applying magnetic fields, offering an efficient approach to accomplish intrinsically coupled functionality in multiferroics.
