7.1.11 Brazilian Prototypes

First reciprocating magnetocaloric device in Brazil was built at the Federal Uni-
versity of Santa Catarina (Table 7.10 ) and presented in 2011 by Trevizoli et al. [ 39 ].

1.65 T. The AMR consisted of Gd plates with a thickness of 0.85 mm, a spacing of
0.1 mm and a total mass of 195.4 g. The device operated at a maximum frequency
of 0.14 Hz. The heat-transfer
