Furthermore, they are one of the first examples of 2D superconductivity in a Kagome model, with superconducting temperature Tc ≅ 1÷2.4 K.
Thus this class of materials provides a very challenging platform to explore the interplay of superconductivity and exotic electronic correlations due to the frustrated geometry of the crystalline structure.
Here we present NMR measurements, that provides a powerful method to explore electronic correlations and their effect in materials with frustrated geometry, on an RbV3Sb5 single crystal. Furthermore, we will discuss the implications of first-principles DFT calculations on the interpretation of our NMR findings.
