The rise of quantum materials observed in the past decades has been a source of great excitement for condensed matter scientists, with the flourishing of new concepts and electronic phases of matter. In quantum magnetism significant efforts have been devoted to the search for new quantum states in condensed matter. In particular the Quantum Spin Liquid (QSL) state has attracted a lot of attention as it shows intriguing collective phenomena such as fractionalized excitations or emergent gauge fields. Here, we propose to use µSR spectroscopy to establish the spin liquid behaviour of a recently synthesized quantum triangular antiferromagnet.
