文摘

The effects of substitution of nitrogen by carbon in ε-Fe2(N1-xCx)1-z are explored. Partial substitution affects magnetic properties and interstitial ordering. The Curie temperature, saturation magnetization and hyperfine fields are increased. Isomer shifts and the c lattice parameter are decreased. Changes in ordering are related to relatively favorable interactions between N and C.
