Metallic local-moment magnetocalorics as a route to cryogenic refrigeration
Abstract Commercial adiabatic demagnetisation refrigerators still employ the same hydrated salts that were first introduced over 85 years ago. The inherent limitations of these insulating magnetocalorics – poor thermal conductivity at sub-Kelvin temperatures, low entropy density, corrosiveness – can be overcome by a new generation of rare-earth based metallic magnetocalorics. …
