Abstract

Effects of high magnetic field annealing on microstructure and multiferroic properties of Bi_1−xLa_xFeO₃ have been investigated. It is found that the grain size of these materials prepared by annealing under a magnetic field becomes small and uniform. The magnetic coercive field of the samples synthesized under a magnetic field is higher than that of the samples prepared in the absence of magnetic field. It is also found that application of a magnetic field during annealing process can suppress the leakage behavior in Bi_1−xLa_xFeO₃. As a result, ferroelectric properties are significantly improved by magnetic field annealing and the Bi_0.85La_0.15FeO₃ specimens heated at 5 T had the best remnant polarization value (2P_r) of 46.8 μC/cm², around 8 times higher than that of the samples fabricated at 0 T.
