Abstract :
The isospinel structural compounds CuIr2−xMxS4 (M=W/Mn) are designed to study the different influences on the 5 d electrons of Ir. W ions acting as W4+ in CuIr2−xWxS4, while Mn ions act as Mn2+ in CuIr2−xMnxS4. The suppression of W4+ on the Peierls-like phase transition is more effective than that of Mn2+. The influences of W4+ and Mn2+ on the magnetization are different. The doping of W4+ causes diamagnetism even before the Peierls-like phase transition in CuIr2−xWxS4 system, while Mn2+ produces a paramagnetic background in the CuIr2−xMnxS4 system.
