This occurs in the low temperature regime dominated by quantum tunnelling, in agreement with previous ac susceptibility investigations. In contrast to the latter, however, μSR is sensitive to all fluctuation modes affecting the lifetime of the spin levels. %G English %2 https://univ-rennes.hal.science/hal-01834012/document %2 https://univ-rennes.hal.science/hal-01834012/file/Tesi_Isotope%20effects%20on%20the%20spin.pdf %L hal-01834012 %U https://univ-rennes.hal.science/hal-01834012 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ SCR-MI-INSA %~ ISCR %~ SCR_OMC2012 %~ ISCR-OMC %~ ISCR-CSM %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ ISCR-CSM-INSA %~ TEST-HALCNRS %~ UR1-MMS %~ TEST2-HALCNRS
