| 中文摘要 | Structural and magnetic properties of the Sm(3)(Fe(1-x)Co(x))(29-y)Cr(y) compounds with x ranging from 0.4 to 1.0 have been investigated by X-ray diffraction and magnetic measurements. It was found that all the compounds are of single phase and crystallize in the Nd(3) (Fe,Ti)(29)-type structure. The higher Co content substituted for Fe requires a higher Cr content to stabilize the 3:29 structure. The Curie temperature T(c) decreases monotonically with increasing Co and Cr contents from 736 K for x=0.4 and y=4.5 to 285 K for x=1.0 and y=7.5. The saturation magnetization M(s) decreases monotonically with increasing Co and Cr contents. It is noteworthy that all the compounds investigated show room temperature easy-axis type of anisotropy and the anisotropy field increases with increasing Co content, going through a maximum at around x=0.8 and y=6.5, then decreases with further increasing Co content. In order to improve the permanent magnetic properties it is necessary to reduce the content of the stabilizing element. (C) 2003 Elsevier B.V. All rights reserved. |
