Local magnetic structure due to inhomogeneity of interaction in S=1/2 antiferromagnetic chain
Masamichi Nishino, Hiroaki Onishi, Pascal Roos +2
We study the magnetic properties of antiferromagnetic Heisenberg chains with inhomogeneity of interaction. Using a quantum Monte Carlo method and an exact diagonalization m…

Temperature dependence of local states due to S=1/2 impurities and their correlation in a S=1 Heisenberg chain
Pascal Roos, Seiji Miyashita
We study the temperature dependence of the low temperature spin configurations, investigating the magnetization profile of the local states due to the impurities and the two point…
