Zero-field incommensurate spin-Peierls phase with interchain frustration in TiOCl
R. Rückamp, J. Baier, M. Kriener +7
We report on the magnetic, thermodynamic and optical properties of the quasi-one-dimensional quantum antiferromagnets TiOCl and TiOBr, which have been discussed as spin-Peierls com…

Unifying Magnons and Triplons in Stripe-Ordered Cuprate Superconductors
G. S. Uhrig, K. P. Schmidt, M. Grüninger
Based on a two-dimensional model of coupled two-leg spin ladders, we derive a unified picture of recent neutron scattering data of stripe-ordered La_(15/8)Ba_(1/8)CuO_4, namely of…
