Quantum magnetism in the stripe phase: bond- versus site order
arXiv:cond-mat/9804012 · doi:10.1103/PhysRevB.59.115
Abstract
It is argued that the spin dynamics in the charge-ordered stripe phase might be revealing with regards to the nature of the anomalous spin dynamics in cuprate superconductors. Specifically, if the stripes are bond ordered much of the spin fluctuation will originate in the spin sector itself, while site ordered stripes require the charge sector as the driving force for the strong quantum spin fluctuations.
