✦ Synopsis

Continuing our work with gadolinium gallium garnet (GGG) after the previously obtained results of 1.2 W at 1.8 K and 45% of the Carnot cycle, we now have accomplished new steps using half of the volume of GGG, a more suitable field profile, improved heat transfer and we have obtained 0.9 W at 2 1 K with efficiency of 64%. We have also computed the competitive threshold values for a magnetic stage refrigerator.
