Commensurate fluctuations in the pseudogap and incommensurate spin-Peierls phases of TiOCl
Abstract
X-ray scattering measurements on single crystals of TiOCl reveal the presence of commensurate dimerization peaks within both the incommensurate spin-Peierls phase and the so-called pseudogap phase above TC2. This scattering is relatively narrow in Q-space indicating long correlation lengths exceeding ∼100Å below T*∼130K. It is also slightly shifted in Q relative to that of the commensurate long range ordered state at the lowest temperatures, …
