7.1.13 Spanish Prototypes

In Spain, the rst reciprocating experimental magnetocaloric device was built at the

University of Coruna, in 2013. Its performance was presented by Gomez et al. [ 41 ].
The magnetic

eld of 1 T was provided a Nd - Fe - B permanent-magnet assembly.

The device had two AMRs lled with Gd plates. The thickness of each plate was
