Abstract
We calculated the electronic structures of substituted cobalt nitrides, that is $FeCo_3N$ and $NiCo_3Ni$, by using the all electron fullpotential linearized augmented plane-wave (FLAPW) energy band method, and investigated the influence on the magnetic properties of $Co_4N$ due to the substitution of Co atom located at corner sites by iron and nickel atoms. We found that the magnetic moments of CoII atoms located at the face-center positions in these compounds are almost same to that of $Co_4N$. The magnetic moments of Fe and Ni atoms in $FeCo_3N$ and $NiCo_3Ni$ are 3.086 and $0.795\;{\mu}_B$, and they have the localized nature of magnetism.
