Abstract
The effects of the Pr additions (10, 20, 25, and 30 at.%) on the magnetothermal properties of polycrystalline metallic Er have been studied using low temperature, high magnetic field heat capacity (4∼120 K, 0∼75 kOe), dc magnetization and ac magnetic susceptibility. These properties include the volumetric heat capacity, the magnetocaloric effect (MCE), the magnetic transition temperatures, the paramagnetic Curie temperatures and the effective magnetic moments. It has been found that Pr additions increase the Curie temperature and decrease the Neel temperature of Er, as well as wipe-out the 26 K and 52 K transitions apparently by merging with the former two transitions. This gives rise to only one MCE peak in each of the Er-Pr alloys, from the broad table-like shape for the Er90Pr10 alloy to the typical narrow caret-like shape for the Er70Pr30 alloy. Pr additions also increase the heat capacity of Er significantly below 18 K. The implications of this higher heat capacity as potential cryocooler regenerator...
