摘要：
Multistep synthesis with X-ray diffraction monitoring of the phase composition has been carried out, optimal synthesis parameters have been determined, and the magnetic properties of solid solutions between thiospinels with ordered tetrahedral A lattices (ferrimagnet Cu0.5Fe0.5Cr2S4 (T-C = 347 K) and antiferromagnet Cu0.5In0.5Cr2S4 (T-N = 35 K) have been studied. Both compounds crystallize in F (4) over bar 3m (T-d(2)) structure. Measurements over wide ranges of fields (0.05-40 kOe) and temperatures (5-300 K) highlighted the nature of magnetism in the samples; new magnetic species have been discovered.
