Abstract

We report here on the observation of superlattice reflections in the new quasi-one-dimensional spin system TiOBr by electron and synchrotron radiation X-ray diffractions. We discussed on crystal symmetry and temperature dependence of superlattice reflections. Superlattice reflections can be observed at ( h, k + frac(1, 2), 0) below Tc 1 and ( h ± δh, k ± δk, 0) above Tc 1; ( h + k = 2 n ). We discussed the origin of two phase transitions, Tc 1 ( = 27 K ) and Tc 2 ( = 47 K ) in TiOBr.
