Abstract
Gadolinium oxide nanoparticles were obtained by the spark discharge electrophysical method. Structure, magnetic and magnetocaloric properties of Gd2O3 nanoparticles are comparatively analyzed. According to X-ray phase analysis, the synthesized Gd2O3 nanoparticles contain two crystallographic phases: cubic and monoclinic. The change in the magnetic part of the entropy dSM was determined from the measurement data of magnetic isotherms based on the Maxwell relation. The maximum value of dSM for a magnetic field variation amplitude of 2 T was approximately 17 J/kgK and was observed at a temperature of 2.5 K.
