文摘

The perovskite system Pb(Fe1−xMnx)2/3W1/3O3 (0 ≤ x ≤ 1, PFMWO) has been synthesized. The structural, magnetic, and dielectric properties of PFMWO have been investigated. The degree of ordering of the Fe and W/Mn cations was found to depend on x. PFMWO behaves as a relaxor ferroelectric below 200 K for low x contents. The antiferromagnetic order of the x = 0 compound becomes short-ranged as x increases.
