Structure and properties of novel ternary Fe-rich rare earth-carbides

Alloying of intermetallic rare-earth compounds of the type R/sub 2/Fe/sub 17/ leads to ternary carbides of the form R/sub 2/Fe/sub 17/C/sub x/. In this work, the authors discuss C-induced changes in Curie temperatures, unit cell dimensions, magnetization, and magnetocrystalline anisotropy. They report on HREM (high-resolution electron microscopy) observations of stacking faults in these materials and discuss their possible influence on the attainment of coercive forces.<
