Experimental study of Hopkinson effect in HDDR-treated Nd15Fe77B8 and Sm2Fe17Nx materials
Source abstract
Abstract
Abstract Emergence and magnitude of the magnetisation maximum due to the Hopkinson effect in the thermomagnetic curve of the hydrogenation-disproportionation-desorption-recombination (HDDR)-treated Nd15Fe77B8 and Sm2Fe17Nx was investigated. For the HDDR-treated Nd15Fe77B8, the magnitude of the magnetisation maximum depended upon the recombination time. For the Sm2Fe17Nx material prepared via the HDDR, however, no obvious correlation between the magnetisation maximum and the recombination time was found.
