The Magnetic Properties of MnxFe1−xNiSi (x=0,0.25,0.5,0.75,1) Alloys

The magnetic properties of Mn x Fe 1− x NiSi ( x =0,0.25,0.5,0.75,1) alloys are studied using density functional theory and the WIEN2k package. The exchange correlation potential is treated by generalized gradient approximation (GGA). The total energy calculations of these alloys confirm the stabili...

Zusammenfassung:The magnetic properties of Mn x Fe 1− x NiSi ( x =0,0.25,0.5,0.75,1) alloys are studied using density functional theory and the WIEN2k package. The exchange correlation potential is treated by generalized gradient approximation (GGA). The total energy calculations of these alloys confirm the stability of the ferromagnetic phase as compared to a nonmagnetic phase. The total magnetic moment is not a linear function of x . By increasing x , it increases and then decreases. The peak position of the magnetic moment is near x =0.75.
