Magnetic entropy change in bulk nanocrystalline Gd metals

The magnetocaloric properties of the as-consolidated nanocrystalline and coarse-grained gadolinium metals were studied in the present work. With the decrease of Gd grains from micrometer to nanometer range, magnetic entropy change drops surprising from 10.07 to 4.47 J kg−1 K−1 at a magnetic-field change of 5 T, and their resultant magnetic entropy change uniformly peaks at 294...
