摘要：

The magnetic hyperfine field (mhf) acting on a Ta-181 probe dilutely substituted at the non-magnetic transition element site has been investigated in the Heusler alloys Co2VGa, Co2NbGa, Co2TaAl and Co2CrAl by TDPAC measurements utilizing the 133-482 keV gamma-gamma cascade in Ta-181 following the beta(-) decay of Hf-181. The results are discussed in terms of the mhf systematics in the cobalt-based Heusler alloys, and are compared with theoretical predictions based on the Blandin and Campbell model.
