Abstract
The magnetic properties of semiconductor CuTi2−2x Cr2x S4 systems have been studied The nearest neighbour J 1x and the nextneighbour superexchange J 2x interactions are evaluated by using the mean field theory for this spinel CuTi2−2x Cr2x S4 system The magnetic energy the intraplanar and the interplanar interactions are deduced The hightemperature series expansion HTSE combined with the Padé approximants method PA is applied to this spinel system to determinate the magnetic phase diagrams ie T C versus dilution x The critical exponents associated with the magnetic susceptibility γ and with the correlation length ν are deduced in order phase
