We aim to explore the groundstate of a new near-perfect S=1/2 kagome antiferromagnetic (KAFM) system using MuSR at the lowest possible temperatures. The title compound is comprised of kagome planes of Cu2+ ions, separated by VO4 tetrahedra and Ba2+ ions. The vertex sharing triangles that make up the kagome network of this material are not equilateral as in the case of Herbertsmithite, but are isosceles like those of Volborthite. Whilst a 3.06% difference in Cu-Cu bond differences of the triangles is observed in the Volborthite, Vesignieite only has a difference of 0.2% making it a much better approximation to a perfect kagome system. An additional benefit to this material is the lack of Zn2+ ions present in Herbertsmithite for anti-site dissorder, leaving a much cleaner system for study than the best current model S=1/2 KAFMs, Volborthite and Herbertsmithite.
