Incommensurability and spin-Peierls transition in TiOBr
What is it about?
TiOBr undergoes a phase transition at Tc2=47.1(4)K towards an incommensurate superstructure and at Tc1=26.8±0.3K it locks in into a twofold superstructure similar to the low-temperature spin-Peierls state of TiOCl.
Why is it important?
Frustration between intra- and interchain interations within the spin-Peierls scenario, and competition between the two-dimensional magnetic order and one-dimensional spin-Peierls order are discussed as possible sources of the incommensurability.
