Skyrmions are topological excitations that exist in a variety of magnetic insulators. Here we propose to complete our previous experiment (RB1320198) with the aim of producing a fast-track publication. The project has already yielded very promising initial results, strongly suggesting that muons are sensitive to the skyrmion lattice phase. We are aware that other groups are also attempting to complete their first muon-studies of the skyrmion lattice phase, and so this beamtime request is an urgent one.
