Dzyaloshinskii-Moriya interaction in NaVO: a microscopic study
arXiv:cond-mat/0006036 · doi:10.1103/PhysRevB.62.14164
Abstract
We present a unified account of magnetic exchange and Raman scattering in the quasi-one-dimensional transition-metal oxide NaVO. Based on a cluster-model approach explicit expressions for the exchange integral and the Raman-operator are given. It is demonstrated that a combination of the electronic-structure and the Dzyaloshinskii-Moriya interaction, allowed by symmetry in this material, are responsible for the finite Raman cross-section giving rise to both, one- and two-magnon scattering amplitudes.
