| Abstract Scope |
Advances in our understanding of magnetocaloric effect (MCE) and magnetocaloric materials will help to employ novel energy efficient cooling technologies such as magnetic refrigeration. Rare earth elements and their compounds are strong potential candidates for application as working materials in magnetic refrigerators, especially in the cryogenic temperature range, due to their strong localized magnetic moments and consequent large magnetization. GdNi is a promising MCE material near 70 K, but to expand its working range chemical substitutions are necessary. We report that in GdNi the substitution of Ni by Co increases the working temperature range of magnetic refrigeration up to ~120 K (liquefaction temperature of natural gas) [1], while the substitution of Gd by Ce offers a cost-effective way to lower the operating range down to ~30 K [2].
