On the Incommensurate Phase of Pure and Doped Spin-Peierls System CuGeO_3
arXiv:cond-mat/9711094 · doi:10.1103/PhysRevB.58.2658
Abstract
Phases and phase transitions in pure and doped spin-Peierls system CuGeO_3 are considered on the basis of a Landau-theory. In particular we discuss the critical behaviour, the soliton width and the low temperature specific heat of the incommensurate phase. We show, that dilution leads always to the destruction of long range order in this phase, which is replaced by an algebraic decay of correlations if the disorder is weak.
