• The magnetocaloric effect (MCE) of BiFeO 3 (BFO)|La 0.7 Sr 0.3 MnO 3 (LSMO) thin films was investigated via phenomenological model. It is revealed that the values of magnetic entropy change, temperature range covering MCE, change of specific heat, and relative cooling power of BFO|LSMO films decrease dramatically with an increase of BFO. The simulation shows furthermore that these BFO|LSMO films have prospective importance in magnetic refrigerants over a wide temperature range, including cryogenic and room temperatures. The MCE parameters of BFO|LSMO films are significantly larger and comparable with some MCE ones of magnetic materials in previous works.
