Multiferroic Studies on La0.7Bi0.3CrO3 Perovskite
Magnetic and dielectric properties on a polycrystalline La0.7Bi0.3CrO3 have been investigated. A canted antiferromagnetic (CAF) phase transition giving weak ferromagnetism at TN = 230K has been observed. M-H at 10K shows non-saturating trend, even up to 5T, confirms the CAF ordering. The permittivity (ε')-vs-temperature (T) variation shows a relaxor ferroelectric (RFE) nature accompanied by a pronounced anomaly in ε'-T at TN. The anomaly in ε'-T at TN indicates the presence of magentoelectric (ME) coupling in this material.
