Spin Density Wave and Superconductivity in Highly Anisotropic Materials. IV. Electromagnetic Properties of the Coexistence Phase

Abstract

The coexistence state of the spin density wave due to the itinerant electrons and superconductivity is further studied focusing on its electromagnetic properties within the same simple electron band model as used previously by the author. Anisotropic penetration depth and static electronic susceptibility are calculated. A brief discussion on recent far-infrared transmission experiments of (TMTSF)₂ClO₄ at low temperatures is given.
