Anisotropy of easy-plane Y2Fe17, Y2Fe17N3 and Sm2Fe17

The magnetocrystalline anisotropy of the easy-plane compounds Y2Fe17, Y2Fe17N3 and Sm2Fe17 are measured. To simplify the analysis of the magnetisation data, the metallic powders are aligned in a magic cylinder device. Based on the Sucksmith-Thompson method, K1 and K2 are determined between 4.2 K and...

Description
Summary:The magnetocrystalline anisotropy of the easy-plane compounds Y2Fe17, Y2Fe17N3 and Sm2Fe17 are measured. To simplify the analysis of the magnetisation data, the metallic powders are aligned in a magic cylinder device. Based on the Sucksmith-Thompson method, K1 and K2 are determined between 4.2 K and room temperature. The values are used to separate the transition metal anisotropy contribution from the rare-earth contribution in Sm2Fe17.
