摘要
The recently discovered (RE)(12)Co5Bi (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 Y12Co5Bi and Gd12Co5Bi. Our results indicate a magnetic transition at around 100 K for Gd12Co5Bi. By contrast, Y12Co5Bi does not show a magnetic transition as expected since Y3+ does not contain any f 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 Gd12Co5Bi. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3059373]
