Magnetization Plateaux in Quasi-One-Dimensional Strongly Correlated Electron Systems: A Brief Review
D. C. Cabra, M. D. Grynberg, A. Honecker +1
This is a short review of recent theoretical work on magnetization plateaux in one-dimensional strongly correlated electron systems, i.e. in spin chains, spin ladders or more gener…
Nishimori point in the 2D +/- J random-bond Ising model
A. Honecker, M. Picco, P. Pujol
We study the universality class of the Nishimori point in the 2D +/- J random-bond Ising model by means of the numerical transfer-matrix method. Using the domain-wall free-energy,…
Magnetic properties of a spin-1/2 quadrumer chain
Andreas Honecker, Wolfram Brenig
We study a novel S=1/2 cluster chain Hamiltonian which has recently been proposed in the context of the charge ordered low-temperature phase of alpha'-NaV2O5. We perform a detailed…
Frustrated trimer chain model and Cu3Cl6(H2O)2 2H8C4SO2 in a magnetic field
A. Honecker, A. Läuchli
Recent magnetization and susceptibility measurements on Cu3Cl6(H2O)2 2H8C4SO2 by Ishii et.al. [J. Phys. Soc. Jpn. 69, 340 (2000)] have demonstrated the existence of a spin gap. In…
Field induced ordering in highly frustrated antiferromagnets
M. E. Zhitomirsky, A. Honecker, O. A. Petrenko
We predict that an external field can induce a spin order in highly frustrated classical Heisenberg magnets. We find analytically stabilization of collinear states by thermal fluct…
