We have calculated the resonance branches and the magnetization curve using a spin Hamiltonian including the interlayer exchange and the Dzyaloshinsky-Moriya (DM) interactions. By putting the same parameter values for the analyses along the c-axis (normal to the kagome plane), the calculated results show satisfactory agreement with the experimental ones. As a result, we have successfully explained all the experimental results with one set of the intra- and the inter-plane exchange and the DM interaction parameters. © 2012 Springer Science+Business Media New York.Mahidol UniversityMaterials SciencePhysics and AstronomyConference PaperSCOPUS10.1007/s10909-012-0759-4
