摘要：
Based on phenomenological model, the effect of TiO2 addition on magnetocaloric effect (MCE) for La0.7Sr0.3MnO3 (LSMO) has been investigated. It is found that at low TiO2 doping decreases slightly magnetocaloric properties. Moreover, LSMO-TiO2 can be tailored to near ambient temperature, which is favorable for magnetic refrigeration that occurs in different temperature ranges. Moreover, MCE of LSMO/TiO2 composites spanning over a broad range of temperature leads to a remarkably wide-working temperature region, which is beneficial for practical applications. These results make the La0.7Sr0.3MnO3-TiO2 samples potential candidates for practical applications.
