Figure 9. (A) The operational principle of magnetic refrigeration equipment. (B and C) Temperature and pressure dependence of the isothermal magnetic entropy change in LaFe11.57Si1.43 and LaFe11.57Si1.43H1.64. Open and closed symbols correspond to magnetic entropy change for a field change of 2 and 5 T, respectively[56].(B and C) are reproduced with the permission of Ref.[56] Copyright 2008, American Physical Society.
