The search for magnetic monopoles in spin ice.

DOI

In recent work Moessner and colleagues have demonstrated that thermally induced defects in spin ice behave as emergent magnetic monopoles. Within the material there exist magnetic "charges" and we suggest that a signature of this may be found by measuring the muon relaxation. Specifically it has been predicted that a high density of magnetic poles will be swept to the surface under applied field. Therefore we would like to measure the field lines emerging from the poles in a thin silver foil adjacent to the sample after a magnetic field has been pulsed on. Moreover once the magnetic field is pulsed off a measurable relaxation is expected. We have previously shown that this method of exterior muon implantation can assist interpreting conventional MuSR measurements as well as providing a useful contrast to bulk magnetization measurements.
