摘要

The magnetocaloric effects of the La0.52Y0.15Ca0.33MnO3-δ compound is reported to cover an extensive temperature range, approaching room-temperature and lower temperatures, making it a viable candidate for magnetic refrigeration. Moreover, the relative cooling power of the La0.52Y0.15Ca0.33MnO3-δ compound reaches 454 J/Kg, surpassing the levels of popular magnetic refrigerants like (La–Sr)MnO3, J/Kg, (La–Sr)MnO3, (La–Ca–Pb)MnO3, and for Gd, and La1-xCaxMnO3 compounds. The La0.52Y0.15Ca0.33MnO3-δ compound can function as an individual magnetic refrigerant in MR at temperatures close to room temperature and below ones. La0.52Y0.15Ca0.33MnO3-δ compound is a promising magnetic refrigerant for different purposes.
