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 stabilize the low symmetric phase with a collinear Néel magnetic ordering. A multivalued dependence of the on-site magnetization as a function of an uniaxial pressure is found.
