W. Zarek, INFLUENCE OF SI, AL AND C ON THE CRYSTAL-STRUCTURE AND MAGNETIC-PROPERTIES OF SM2FE17, Journal of magnetism and magnetic materials, 158, 1996, pp. 91-92
The crystal structure and magnetic properties of Sm2Fe17Siy, Sm(2)Fe(1
7-x)M(x) (M = Si, Al) and Sm2Fe17-xAlxCy for y less than or equal to 2
and x < 4 were investigated. It was found that increasing the Al or S
i concentration causes a rise in the Curie temperature and a decrease
in the magnetic moment. Compounds with Al and Si with x > 3 and Sm2Fe1
7-xAlxCy exhibit axial anisotropy at room temperature.
