Multicaloric effect in bismuth ferrite

The caloric effects in bismuth ferrite were estimated using well-known models for the prediction of magnetocaloric and electrocaloric effects from the analysis of magnetization and permittivity data. In the temperature range of 630–645 K, the maximums of magnetocaloric and electrocaloric characteristics were observed, which indicate an enhanced magnetoelectric interaction in this region. The observed coupled caloric phenomena can be attributed to multicaloric effects and bismuth ferrite — to multicalorics.
