Abstract
The structural, magnetic, and magnetocaloric characteristics of the nanosized La0.4Gd0.2Sr0.4MnO3 manganites were discussed based on the influence of heating temperature (700 and 1000 °C). We investigated it, further, to present the strong link between magnetic refrigeration and hyperthermia technique. Both samples are nanosized according to the study of the scanning electron microscopy and the X-ray diffraction patterns (Scherrer and Williamson-Hall plots). Analyzing the thermal evolution of the magnetizations proves that various magnetic states are present in both samples, superparamagnetism, spin-glass, ferromagnetism, and paramagnetism. We demonstrated that the Curie temperature is between 318 and 331 K, which is the ideal range for the hyperthermia approach. The relative cooling power at 6 T is around 404.085 J/Kg for LGSM_1000; thus, this sample is an excellent candidate for magnetic cooling. It is a great achievement result that the rate of evolution from LGSM_700 to LGSM_1000 is 3213.26 %.
