| Abstract: | MnS and MgS form a solid solution with the NaCl structure. MnS is antiferromagnetic with first neighbour antiferromagnetic interactions which can never be fully satisfied because in the fcc lattice of the Mn cations first neighbours have mutual first neighbours. This competing interaction condition can lead to spin glass behaviour in a system disordered on the cation lattice. We present magnetic susceptibility and neutron powder diffraction data which suggest that with the addition of MgS to MnS, to produce a disordered cation lattice, the antiferromagnetic phase may have a reentrant spin glass phase at low temperatures and that certainly at the composition Mn0 3SMg0 63S the material is a classic spin glass. |
