The recently discovered (where RE is a rare earth element) system has rich magnetic phase diagrams. We applied muon spin relaxation to study the local magnetism in polycrystalline samples of and . Our results indicate a magnetic transition at around for . By contrast, does not show a magnetic transition as expected since does not contain any electrons. These results are consistent with the dc susceptibility measurements. We also estimate and discuss the fluctuation rates in the high temperature paramagnetic regime for .
