Abstract
The superstructure parameters For the Cu0.5Fe0.5Cr2S4 and Cu0.5In0.5Cr2S4 c ompounds have been determined by neutron and X-ray diffraction. The locaize d magnetic moments in different sublattices measured for Cu0.5Fe0.5Cr2S4 ar e equal to 3.06 +/- 0.17 muB for Fe3+ ions in the A-site and 2.76 +/- 0.22 muB for Cr3+ ions in the B-site (Cu+ possess no magnetic moment), which are much less than the magnetic moments for the ions in the purely ionic state .
