Abstract

Several M₃TeO₆ (M = Mn, Co, Ni, Cu) oxides order antiferromagnetically at low temperatures (≲60 K), while displaying interesting dielectric properties at high temperatures (ferroelectricity below 1000 K in M = Ni case). We have investigated and analyzed the structural and magnetic properties of Mn-doped Co₃TeO₆ and Ni₃TeO₆, which order antiferromagnetically at temperatures higher than their undoped counterparts.
