High-performance low-temperature magnetic refrigerants made of gadolinium-hydroxy-chloride†
Abstract
A recipe for facile preparation of high-performance low-temperature magnetic refrigerants based on gadolinium-hydroxy-chloride (GHC), which exhibits a large magnetic entropy change of up to 61.8 J kg−1 K−1 or 318.9 mJ cm−3 K−1, high thermal stability, strong alkali-resistance and good thermal conductivity, is reported.
