NMR and EPR measurements in the two-dimensional frustrated anti-ferromagnets on a square lattice Li2VOSiO4 and VOMoO4 are presented. It is found that a structural distortion, possibly driven by the frustration, takes place in both compounds. The modifications induced by the distortion in the NMR and EPR spectra on cooling can be accounted for by a progressive growth of the size of the domains where the lattice is distorted.

Abstract

NMR and EPR measurements in the two-dimensional frustrated anti-ferromagnets on a square lattice Li2VOSiO4 and VOMoO4 are presented. It is found that a structural distortion, possibly driven by the frustration, takes place in both compounds. The modifications induced by the distortion in the NMR and EPR spectra on cooling can be accounted for by a progressive growth of the size of the domains where the lattice is distorted.
