Abstract

We present a new member of the multiferroic oxides, Lu2MnCoO6, which we have investigated using X-ray diffraction, neutron diffraction, specific heat, magnetization, electric polarization, and dielectric constant measurements. This material possesses an electric polarization strongly coupled to a net magnetization below 35 K, despite the antiferromagnetic ordering of the S = 3/2 Mn4+ and Co2+ spins in an arrow up}arrow up}arrow down}arrow down} configuration along the c-direction. We discuss the magnetic order in terms of a condensation of domain boundaries between arrow up}arrow up} and arrow down}arrow down} ferromagnetic domains, with each domain boundary producing a net electric polarization due to spatial inversion symmetry breaking. In an applied magnetic field the domain boundaries slide, controlling the size of the net magnetization, electric polarization, and magnetoelectric coupling.
