摘要：
This study concerns the magnetic properties of single crystals of Fe (x) Mn1 - x In2S4 alloys. The basically antiferromagnetic character of indirect exchange interactions between Fe2+ and Mn2+ cations is established. As the concentration of Fe2+ cations is increased, the magnetic ordering temperature increases from similar to 12 K (x = 0) to similar to 22 K (x = 1). Short-range-order ferromagnetic correlations are observed. The basic magnetic phase state of the alloys is the spin glass state, with the freezing temperature increasing from similar to 5 K (x = 0) to similar to 12 K (x = 1). As the external magnetic field is increased, the magnetic ordering temperature slightly decreases. The most probable causes and mechanisms of formation of the magnetic state of the alloys are discussed.
