Enhanced magnetic fluctuations in doped spin-Peierls systems: A single-chain-model analysis
We analyze by means of the real-space renormalization group (RG) as well as by exact diagonalizations the properties of a single-chain model of a doped spin-Peierls system, where a major role is played by the localized moments created by the impurities. By the RG flow, we are able to follow …
