Abstract

Long range 1:1 cation order was developed in Pb(Fe2(1-x)/3Sc2x/3W1/3)O-3 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 (similar to 0.61 mu(B)/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 similar to 15 mu C/cm(2) at 40 kV/cm at 120 K. (c) 2007 American Institute of Physics.
