YbVSn has a HfFeGe-type structure, in which V atoms form a Kagome lattice and Yb atoms form a triangular lattice. This rare Yb-based Kondo triangular lattice system has attracted much attention as an essential model to explore the relationship between quantum magnetism and topological properties. To microscopically clarify the quantum criticality of this system, we have performed V nuclear magnetic resonance (NMR) studies using a single crystal of YbVSn. In this talk, I will report on the spectral assignments of V nuclei revealed from V NMR measurements in the paramagnetic state.
