|Title:||Cation, dipole, and spin order in Pb (Fe23 W13) O3 -based magnetoelectric multiferroic compounds|
R. W. McCallum
|Keywords:||Physics and Astronomy|
|Abstract:||Long range 1:1 cation order was developed in Pb (Fe2 (1-x) 3 Sc2x3 W13) O3 solid 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 (∼0.61 μB f.u.) was observed for x=0.15 at 10 K under 5 T. A ferrimagnetic structure was suggested to take into account for the observed magnetic behavior. These compounds also display a saturated electrical polarization of ∼15 μC cm2 at 40 kVcm at 120 K. © 2007 American Institute of Physics.|
