Cation, dipole, and spin order in Pb(Fe2/3W1/3)O3-based magnetoelectric multiferroic compounds

Long range 1:1 cation order was developed in Pb(Fe2(1−x)/3Sc2x/3W1/3)O3solid solution compounds by high temperature solid state reaction. It is found that the degree of cation order directly influences the saturation magnetization in these single phase compounds. A high saturation magnetization (∼0.61μB/f.u.) was observed for x=0.15 at 10Kunder 5T. A ferrimagnetic structure was suggested to take into account for the observed magnetic behavior. These compounds also display a saturated electrical polarization of ∼15μC/cm2 at 40kV/cm at 120K
