This is a proposal to investigate magneto electric (ME) effects in Cr2O3, which belongs to a class of materials in which electric and magnet properties are strongly coupled. For example applying an electric field induces a change in the magnetic properties. Furthermore, recent theoretical work suggests that an electric charge positioned inside a ME material has properties which resemble those of a magnetic monopole. The positive muon and associated technique of muon spin rotation is a novel probe of such effects since the muon acts both as an isolated charge and a sensitive local magnetic probe.
