Criticality in a disordered quantum antiferromagnet by neutron diffraction
E. Wulf, D. Huvonen, J. -W. Kim +5
Field-induced magnetic ordering in the structurally disordered quantum magnets Ni(ClBr)4SC(NH), % and 13%, is studied by means of neutron diffra…
Impact of strong disorder on the static magnetic properties of the spin-chain compound BaCu2SiGeO7
T. Shiroka, F. Casola, W. Lorenz +3
The disordered quasi-1D magnet BaCu2SiGeO7 is considered as one of the best physical realizations of the random Heisenberg chain model, which features an irregular distribution of…
Symmetric and asymmetric excitations of a strong-leg quantum spin ladder
D. Schmidiger, P. Bouillot, G. Ehlers +5
The zero-field excitation spectrum of the strong-leg spin ladder (CHN)CuBr (DIMPY) is studied with a neutron time-of-flight technique. The spectrum is decomposed i…
Dirty-boson physics with magnetic insulators
Andrey Zheludev, Tommaso Roscilde
We review recent theoretical and experimental efforts aimed at the investigation of the physics of interacting disordered bosons (so-called dirty bosons) in the context of quantum…
Magnetic structure of the frustrated S=1/2 chain magnet LiCu2O2 doped with nonmagnetic Zn
A. A. Bush, N. Büttgen, A. A. Gippius +7
We present the results of magnetization, ESR and NMR measurements on single crystal samples of the frustrated S=1/2 chain cuprate LiCu2O2 doped with nonmagnetic Zn^2+. As shown by…
