Description

I will discuss muon spin rotation (muSR), nuclear magnetic resonance (NMR) and thermodynamic measurements on several Mo3O8-based cluster Mott insulators consisting of a 1/6th-filled breathing Kagome lattice. Depending on sometimes subtle structural differences between these various materials, a number of different magnetic phases can be stabilized, including possible quantum spin liquids: a long-range entangled state with emergent fractionalized excitations.
