In the condensed matter community the last ten years have seen a revolution in our understanding of how topology influences the properties of solids. A famous example from the last couple of years is the class of Weyl semi-metals. These are solids, such as TaAs (as demonstrated in 2015), which have various unusual properties driven by the presence of "Weyl points" in their electronic band structure. These Weyl points may also exist in the magnetic excitations of materials leading to analogous unusual properties which have not yet been explored simply because concrete examples have not been established. This proposal, which is motivated by calculations of the spin waves and Berry curvature on a well characterized antiferromagnet, is to see these Weyl points in a real magnetic insulator for the first time.
