Vesignieite, Cu3VBa2O8(OH)2, is one of very few materials approximating a kagome spin-1/2 Heisenberg antiferromagnet, a model that is the ideal setting for novel quantum spin liquid physics. Nonetheless, it shows a transition at 9 K to a heterogeneous ground state consisting of a dynamic spin liquid component and a weakly static fraction. To better understand the precise nature of this exotic ground state and guide future theoretical work, we propose to measure a series of Vesignieite samples diluted with non-magnetic Zn to test the effects of in-plane disorder on the frozen fraction, spin dynamics and other magnetic properties.
