Static impurities in the S=3/2 kagome lattice
A. Laeuchli, S. Dommange, B. Normand +1
We consider the effects of doping the S=3/2 kagome lattice with static, nonmagnetic impurities. By exact diagonalization calculations on small clusters we deduce the local spin cor…
Field Induced Staggered Magnetization and Magnetic Ordering in
M. Clemancey, H. Mayaffre, C. Berthier +6
We present a D NMR investigation of the gapped spin-1/2 compound . Our measurements reveal the presence of a magnetic field induced transverse sta…
Plaquette valence bond solid in the frustrated Heisenberg quantum antiferromagnet on the square lattice
M. Mambrini, A. Laeuchli, D. Poilblanc +1
Using both exact diagonalizations and diagonalizations in a subset of short-range valence bond singlets, we address the nature of the groundstate of the Heisenberg spin-1/2 antifer…
Dynamic spin Jahn-Teller effect in small magnetic clusters
M. Elhajal, F. Mila
We study the effect of spin-phonon coupling in small magnetic clusters, concentrating on a S=1/2 ring of 4 spins coupled antiferromagnetically. If the phonons are treated as classi…
LiVO(Si,Ge)O, a prototype of a two-dimensional frustrated quantum Heisenberg antiferromagnet
R. Melzi, P. Carretta, A. Lascialfari +4
NMR and magnetization measurements in LiVOSiO and LiVOGeO are reported. The analysis of the susceptibility shows that both compounds are two-dimensional Hei…
