Electron-Spin-Susceptibility Studies of Tetrathiafulvalene Tetracyanoquinodimethane (TTF-TCNQ)

Abstract

The temperature dependences of the spin susceptibility in TTF-TCNQ as measured by static and ESR techniques are in close agreement in the temperature region 30-300 K. This result indicates that the spin-resonance experiment interrogates both molecular chains, even at temperatures where at least one chain displays metalliclike properties.
