A thermomagnetic analysis of an eco-friendly nano-sized dysprosia for energy efficient cryo-cooling systems

Abstract

metal ions, which play a major role in the structural distortion of doped NSDs. The magnetic studies of NSDs revealed that antiferromagnetic and ferromagnetic properties exhibited predominantly at low temperature, whereas at high-temperature, paramagnetic properties are observed. It was also found that the magnetic entropy change of NSDs at the applied magnetic field is comparatively higher, making them a suitable material for eco-friendly cryogenic systems.
