Abstract ：The effects of N substitution on the magnetic properties of Mn3 InC1?x Nx ≤x≤ 0.7) are investigated systematically. Partial substitution of N for C leads to the monotonic reduction in both the Curie temperature TC and saturated magnetization MS . The final results obtained from thermo-magnetic curves demonstrate that Mn3 InC1?x Nx 3 InC at 100 Oe and 5000 Oe indicate the metastability and the coexistence of different magnetic phases at lower temperature. The spans of FIM phase broaden gradually with further N doping. The mechanism for the induction of the complicated magnetic state is still in controversy. However, the results clearly show that the doping at the X site in antiperovskite Mn3 AX materials is as useful as that of the A and Mn sites.
