Description
Kagome antiferromagnets are well-established model systems in theoretical condensed matter research. Experimental verification of theoretical solutions is, however, lacking, as real systems obeying strict conditions of the ideal Kagome lattice are sparse. In the RAgGe family of compounds, frustrated magnetism is induced by the distorted Kagome arrangement of the rare earth R$^{+3}$ ions, influenced by strong magnetic easy-axis anisotropy and itinerant electrons. Here, we present single crystal neutron diffraction results for the R = Yb and Tm compounds and discuss approaches to investigate possibilities of topological and multi-k feature.
