Abstract

Transport and static magnetic susceptibility of charge transfer organic alloys show a well defined second order phase transition at temperatures between T//c equals 215K for x equals 0 and T//c equals 155K for x equals 0. 75. The high temperature phase appears to be a low mobility metal with a conductivity of 1( OMEGA cm)** minus **1 along the chain direction and a relatively high density of states at the Fermi level as reflected by the nearly temperature independent large susceptibility. These properties are insensitive to alloying. The origin of this 'metallic' behavior, which is unusual for charge transfer salts with TCNQ molecules grouped into tetrads along the chains, is discussed and tentatively ascribed to the influence of the Coulomb potential from the donor molecules.
