Abstract
The magnetic structure of NiS2-xSex has been investigated by Mossbauer effect of 57Fe doped NiS2-xSex. Mossbauer patterns of the non-collinear first-kind ordering of FCC have been observed both in metallic and semiconductive antiferromagnetic phases. The local environment effect on the magnetic moments is weak in this system; the magnetic moments decrease uniformly at all nickel sites by selenium substitution. With increasing x the magnetic moments decrease without any discontinuous change at the metal-semiconductor phase boundary. The magnetic moment of nickel rotates towards the (111) direction with increasing temperature in NiS1.6Se0.4.Keywords
