RNi (R = Gd and Dy) Compound-Based Magnetocaloric Materials

Abstract

High-performance materials for solid-state magnetic cooling in the temperature range of 1.5–100 K were developed. The magnetic and magnetocaloric properties of the new (R, R')Ni (R = Gd and R' = Dy) compounds and their hydrides were studied in the Curie temperature region. The main regularities in the behavior of the temperature dependences of the magnetocaloric effect for different compositions were established.
