Effect of Heavy Rare Earth Dopants on Hydrogen Incorporation in SmCo 2:17 Type Magnet
Previous studies showed that the temperature coefficient of obviously decreases with increasing the content of heavy rare earth element in SmCo magnet. But the investigation on the hydrogen incorporation in SmCo magnet is limited. In this paper, we would like to report the effect of heavy rare earth dopant on hydrogen incorporation in SmCo 2:17 type magnet. The relationship between temperature and pressure in hydrogenatied magnet is studied using XRD, DTA, and magnetic measurement. Based on the experimental results, the initial hydrogenation temperature decreases with increasing the content of heavy rare earth, however, the initial saturation pressure enhances. During the hydrogenation, the temperature region shrinks with increasing heavy rare earth doping.
