Abstract
The effect of different spinless solvents on the magnetism of V(TCNE)x . y(solvent) (TCNE=tetracyanoethylene) is studied by temperature (T) dependent ac susceptibility above 2.3 K. Though V(TCNE)x . y(CH2Cl2) h as a critical temperature T(c) approximately 400 K, for V(TCNE)x . y(C 4H8O), T(c) approximately 205 K and the coercive field is reduced, whi le for V(TCNE)x . y(CH3CN), T(c) approximately 140 K or below and a sp in glass phase exists below a spin freezing temperature of T(f) approx imately 7-15 K. The variations with solvent are suggested to be due to spin dilution and random anisotropy introduced by the spinless solven ts.
