1. The magnetocaloric effect and its applications
This first part is an introduction to the magnetocaloric effect and its main applications. It gives an overview of the magnitudes characteristic of the materials and the objectives associated with their development.
1.1 Principle of the magnetocaloric effect
The magnetocaloric effect (MCE) is an intrinsic property of magnetic substances that manifests itself as a reversible temperature change when subjected to a magnetic field. This effect is maximal around the magnetic ordering temperature, or transition temperature (this may be the Curie temperature for ferromagnetic ordering, or the Néel temperature for antiferromagnetic or ferrimagnetic ordering). At this point, the variation in the magnetization of the material undergoing magnetic ordering is maximal, resulting...
