Magnetocaloric effect in nanostructured Pr2Fe17 and Nd2Fe17 synthesized by high-energy ball-milling

"Nanocrystalline Pr2Fe17 and Nd2Fe17 powders with rhombohedral Th2Zn17-type crystal structure and average particle sizes around 20 nm have been obtained by high-energy ball milling While the bulk alloys show a well-defined and sharp drop in the low-field magnetization curve at the Curie tempera...
