C. Goldenberg et A. Aharony, EXPLANATION OF NMR EXPERIMENTS ON DOPED CUPRATES USING THE FRUSTRATION MODEL, Physical review. B, Condensed matter, 56(2), 1997, pp. 661-667
The doping dependence of the Cu NMR line shapes measured in YBa2Cu3O6x is explained by a planar antiferromagnetic XY model with quenched fr
ustrated ferromagnetic bonds. A numerical algorithm for finding the gr
ound state of the model is described, as well as a method for comparin
g the numerical results to the experiments. Good agreement with the ex
periments is obtained.
