The formation, structure,stability and intrinsic magnetic properties of these carbides were studied. The experimental re-sults show that these carbidek are stable at high temperatures. With increasing carbon concen-tration x, their crystal structure changes from the hexagonal Th_2Ni_17-type to rhombohedralTh_2Zn_(17)-type. The introduction of interstitial carbon atoms results in the expansion of theunit cell volumes and the increase of the room temperature saturation magnetization andCurie temperature. The (Er_(1-x)Sm_x)_2Fe_17C_y carbides with y≥1.0 are found to have an easyc-axis anisotropy at room temperature.
