Effects of spin-elastic interactions in frustrated Heisenberg antiferromagnets
arXiv:cond-mat/0003280 · doi:10.1103/PhysRevB.62.8604
Abstract
The Heisenberg antiferromagnet on a compressible triangular lattice in the spin- wave approximation is considered. It is shown that the interaction between quantum fluctuations and elastic degrees of freedom stabilizes the low symmetric L-phase with a collinear Neel magnetic ordering. Multi-stability in the dependence of the on-site magnetization on an unaxial pressure is found.
