摘要：

We have discovered that Si is able to stabilize the structure of the 2:17-type carbides. The carbides, R2Fe15Si2Cx (R=Sm and Er), were made by heating powders of R2Fe15Si2 in CH4 at 700-degrees-C. For Sm2Fe15Si2C2.3, the Curie temperature is 630 K and the anisotropy field is estimated to be over 70 kOe at room temperature; however, the saturation magnetization is relatively low, only about 88 emu g-1, also at room temperature.
