Abstract

We are requesting 12 shifts of beam time to study the magnetism in two frustrated rhodium pyrochlores. These are new materials that have not been previously studied. The moments are J = 1/2, and as such, the magnetism is expected to be weak. Thus, muSR is the ideal probe to study the magnetism in these systems.
