2. Magnetocaloric effects and materials
In this chapter, we introduce the magnetocaloric effect through a thermodynamic description. Next, methods for characterizing the parameters describing a magnetocaloric material are briefly introduced. Finally, we review the state of the art of materials available on an industrial or laboratory scale, comparing two key parameters ΔS iso and ΔT adia for field variations around 1 Tesla.
2.1 Magnetocaloric effect
The magnetocaloric effect manifests itself as a reversible thermal response (i.e. variation in temperature/entropy) of a material due to the action of a magnetic field. In a very simplified way, a magnetic material can be represented as a crystalline lattice with...
