Abstract
The magnetic properties of single-phase 2:17 compounds of the composit ion Sm2Fe17-xGaxHy were investigated. The substitution of Ga for Fe in the Sm2Fe17 compound resulted in a substantial increase in the Curie temperature and, for alloys with x > 2, the formation of a uniaxial ma gnetic anisotropy at room temperature. The diffusion of hydrogen into those compounds that exhibit an easy axis anisotropy causes a transiti on back to a planar anisotropy. This indicates that the presence of in terstitial hydrogen is detrimental to the hard magnetic properties of these materials.
