Abstract
Single-crystal elastic and inelastic neutron-scattering experiments are performed on the frustrated ferro-antiferromagnet SrZnVO(PO4)2 in high magnetic fields. The fully polarized state, the presaturation phase and the columnar-antiferromagnetic phase just below the presaturation phase were investigated. The observed renormalization of spin-wave bandwidths, re-distribution of intensities between different branches and nonlinearities in the magnetization curve are all indicative of strong deviations from classical spin-wave theory. The previously observed presaturation transition is attributed to a staggered pattern of Dzyaloshinskii-Moriya interactions.
