Abstract
The magnetic properties of the layered compounds FePS 3, NiPS 3 and the mixed systems Fe 1− x Ni x PS 3 have been investigated. All the compounds show a maximum in χ at a temperature T max followed by the onset of antiferromagnetic order at low temperatures at T N. As the composition is changed there is a continuous change in T N and in the ratio T N T max . Our results show that in the mixed antiferromagnetic system Fe 1− x Ni x PS 3, the strongly antisotropic Fe component imposes its anisotropy on the weakly anisotropic Ni component. We find also no frustration or spin-glass-like ordering at any composition.
