Notes:
Magnetic transitions and structural transformations have been investigated in CuIr2S4−xSex (0≤x≤4). It is found from magnetic, resistivity, and thermopower studies that the transition temperature decreases as the Se concentration is increased. The change in magnetization occurs over a 10–15 K range at lower Se concentration, while it broadens to 30 K for an Se concentration of x=0.5. Low-temperature studies proved that beyond the composition corresponding to x=0.5 the cubic structure is stabilized. The metal-insulator transition beyond the x=0.5 composition arises from the electronic rather than from the lattice contribution. © 1998 American Institute of Physics.
