Abstract
The structural and magnetic properties of fine Fe-B particles with a s ize of about 50 nm and B concentrations of 5, 14, and 17 at.% were stu died in as-prepared samples and after annealing in vacuum and in H-2 a tmosphere. The samples annealed in vacuum were found to be dominated b y alpha-Fe in the high B concentrations. Oxide components appear in th e particles with low B content. Boron is found to prevent oxidation of the as-made samples and promote the formation of mixed valence oxides in the crystallized samples.
