The stabilization of the ferromagnetic state in N-doped Fe0.98V0.02S2 is observed due to the incorporation of N impurity.

And the ferromagnetic state connected to the half metal is potentially utilized in spintronic field.
In Fe0.98Cr0.02S1.97N0.03, the 3% of N induced a hybridization between (Cr[3d] and N[2p]). We predicted an enlargement of the peak of the Cr[3d]. In addition, the total moment of the studied systems is augmented as well as the Curie temperature (TC).
