The electrical conductivity of two linear-chain organic compounds in their semiconducting states is found to increase drastically witht the application of electric fields of ∼ 10 mV/cm and with the increase of frequency to ∼ 10 GHz. Also, the electron-spin-resonance line is found to switch abruptly from unresolvable to fully resolved (narrow and metal-like) at fields of 0.1 V/cm. One speculative explanation of these observations is the presence of spin-density waves.
