Destruction of density-wave states by a pseudo-gap in high magnetic fields: application to (TMTSF)${}_2$ClO${}_4$

Abstract

A model is presented for the destruction of density-wave states in quasi-one-dimensional crystals by high magnetic fields. The model is consistent with previously unexplained properties of the organic conductors (TMTSF)${}_2$ClO${}_4$ and (BEDT-TTF)${}_2$MHg(SCN)${}_4$ (M=K,Rb,Tl). As the magnetic field increases quasi-one-dimensional density-wave fluctuations increase, producing a pseudo-gap in the electronic density of states near the transition temperature. When the pseudo-gap becomes larger than the mean-field transition temperature formation of a density-wave state is not possible.
