Abstract

The structural, magnetic and magnetocaloric effect (MCE) properties were studied in DyCoO3 nanoparticles. The synthesized DyCoO3 nanoparticles were approximately 200 nm in size with a typical orthogonal perovskite structure. DyCoO3 possesses an antiferromagnetic ordering at TN = 3.9 K. In magnetic field changes of 0–60 kOe, a giant maximum magnetic entropy change of 16.6 J/kg K and a relative cooling power of 354 J/kg were obtained around TN. These results suggest that DyCoO3 nanoparticles could be regarded as promising candidate for low temperature magnetic refrigerants. [ABSTRACT FROM AUTHOR]
