Abstract

We report ferrimagnetism and reentrant relaxor ferroelectricity near room temperature in a Yb-doped PbFe_2/3W_1/3O₃ cubic perovskite. Structural analysis reveals the presence of a single cubic perovskite phase, with the Fm 3 m space group [lattice parameter: a = 8.0112(3) Å], and partial B-site ordering. The B-site ordering yields uncompensated magnetic moments in the antiferromagnetic structure of PbFe_2/3W_1/3O₃ and ferrimagnetism near room temperature. An excess moment of ∼0.6 μ_B/B-site may be estimated from magnetic hysteresis curves recorded up to 50 kOe at 5 K. The temperature dependent magnetodielectric study reveals a sequential phase transition from a long-range ferroelectric state (across 280 K) to a short-range relaxor ferroelectric state (across 190 K). The long-range ferroelectric ordering is found to be more affected by the application of external magnetic fields than the relaxor phase.
