Ising Like Order by Disorder In The Pyrochlore Antiferromagnet with Dzyaloshinskii-Moriya Interactions
Benjamin Canals, Maged Elhajal, Claudine Lacroix
It is shown that the mechanism of order out of disorder is at work in the antisymmetric pyrochlore antiferromagnet. Quantum as well as thermal fluctuations break the continuous deg…
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…
Ordering in the pyrochlore antiferromagnet due to Dzyaloshinsky-Moriya interactions
M. Elhajal, B. Canals, R. Sunyer i Borrell +1
The Heisenberg nearest neighbour antiferromagnet on the pyrochlore (3D) lattice is highly frustrated and does not order at low temperature where spin-spin correlations remain short…
Dzyaloshinsky-Moriya-Induced Order in the Spin-Liquid Phase of the S=1/2 Pyrochlore Antiferromagnet
Valeri N. Kotov, Maged Elhajal, Michael E. Zhitomirsky +1
We show that the S=1/2 pyrochlore lattice with both Heisenberg and antisymmetric, Dzyaloshinsky-Moriya (DM) interactions, can order antiferromagnetically into a state with chiral s…
Ising transition driven by frustration in a 2D classical model with SU(2) symmetry
C. Weber, L. Capriotti, G. Misguich +3
We study the thermal properties of the classical antiferromagnetic Heisenberg model with both nearest () and next-nearest () exchange couplings on the square lattice by e…
