Effect of Spin-1 Impurities in Dimerized Heisenberg Chains
P. M. Hansen, J. A. Riera, A. Delia +1
The effects of spin-1 impurities introduced in dimerized antiferromagnetic spin chains are studied using Lanczos diagonalization and quantum Monte Carlo simulations. Firstly, the m…

Enhancement of Antiferromagnetic Correlations Induced by Nonmagnetic Impurities: Origin and Predictions for NMR Experiments
Markus Laukamp, George Balster Martins, Claudio J. Gazza +5
Spin models that have been proposed to describe dimerized chains, ladders, two dimensional antiferromagnets, and other compounds are here studied when some spins are replaced by sp…
