Abstract
The magnetic properties of layer AB2X4 compounds, having a ZnIn2S4-type structure, are discussed considering them as possible models for two-dimensional magnetic systems. MnAL2S4, MnAL2Se4 and FeGa2S4 do not appear to be good model systems because the magnetic ions are distributed among tetrahedral as well as octahedral sites of the structure. Their magnetic properties are better understood in terms of short-range magnetic order arising from the presence of isolated clusters. The magnetic behaviour of Co .46Zn .54In2S4, crystallizing in space group R3m, can be explained in the same way.
Only in CrGa1.67S4 do the magnetic Cr3+ ions lie in a triangular planar lattice and, therefore, the magnetic properties are interpreted in terms of a 2-d magnetic system in the temperature range 80 ⩽ T ⩽ 300K.
