Chain breaks and the susceptibility of Sr_2Cu_{1-x}Pd_xO_{3+δ} and other doped quasi one-dimensional antiferromagnets
J. Sirker, N. Laflorencie, S. Fujimoto +2
We study the magnetic susceptibility of one-dimensional S=1/2 antiferromagnets containing non-magnetic impurities which cut the chain into finite segments. For the susceptibility o…

Quantum Magnetic Impurities in Magnetically Ordered Systems
A. H. Castro Neto, E. Novais, L. Borda +2
We discuss the problem of a spin 1/2 impurity immersed in a spin S magnetically ordered background. We show that the problem maps onto a generalization of the dissipative two level…
