Popis:	A new series of interstitial ThMn 12 -type carbides of the formula RFe 10.5 Mo 1.5 C x (R=rare earth) were prepared by sintering the starting intermetallic compounds with carbon powder at T =873 K. The maximum relative volume increase of the unit cell upon the carbon insertion ranges from 1.4% with Pr and Sm to 3.3% with Y, Ho and Er. Depending on the R element and the amount of carbon, the Curie temperature increases from 65 to 140 K in comparison with the pure alloys. Whereas the axial anisotropy is enhanced for the Nd, Tb, Dy and Ho, the easy magnetization direction (EMD) changes from axial to easy plane for the Y, Gd and Er carbides.
