Journal ArticleThe 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) has a critical temperature Tc -400 K, for V(TCNEx.y(C4H8O), Tc -205 K and the coercive field is reduced, while for V(TCNE)x.y(CH3CN), Tc -140 K or below and a spin glass phase exists below a spin freezing temperature of Tf- 7-15 K. The variations with solvent are suggested to be due to spin dilution and random anisotropy introduced by the spinless solvents
