    • Abstract

       

      Monophasic compounds with composition Fe1−x Cux Cr2Se4 (0≤x≤0·2) have been prepared. The compounds have defect nickel arsenide structure. The compositions are semiconductors with low energy of activation. Their Seebeck coefficients are temperature-independent. The compositions x=0 and 0·1 show temperature independent paramagnetism except for a small hump around 210 K. The peculiar behaviour of the susceptibility-temperature plot for the composition x=0·2 is not understood.
