摘要

The recently discovered (RE)_(12)Co_5Bi (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 Y_(12)Co_5Bi and Gd_(12)Co_5Bi. Our results indicate a magnetic transition at around 100 K for Gd_(12)Co_5Bi. By contrast, Y_(12)Co_5Bi does not show a magnetic transition as expected since Y~(3+) 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 Gd_(12)Co_5Bi.
