Cation partitioning in ternary vanadium sulfides₂S₄ (A=Ti, Cr, Fe, Ni)

Abstract

A combination of time-of-flight powder neutron diffraction and powder X-ray diffraction has been used to investigate changes in the cation distribution in a series of isostructural (space group I2/m a≈5.9, b≈3.3 c≈11.3Å, β≈92°) ternary vanadium sulfides, AV₂S₄ (A=Ti, Cr, Fe, Ni). A progressive change from an inverse Cr₃S₄ structure, when A is drawn from the left of the transition series, to a normal Cr₃S₄ structure, when A is drawn from the right of the series, occurs. The magnetic susceptibility of all materials has a significant temperature-independent component and both spin-glass behaviour [A=Cr, T_g=15(3) K] and long-range magnetic order [A=Fe, T_N=135(3) K] are observed.
