Abstract

The magnetic hyperfine field acting on Ta at the non-magnetic transition element site has been investigated in the Heusler alloys Co2(Sc, Hf, V)Sn, Co2ScGa, Co2(V, Nb)Al and Co2Ti(Si, Ge) by TDPAC measurements utilizing the 133–482 keV gamma-gamma cascade in181Ta following the β decay of181Hf. An important conclusion is that the reduced mhf either on the non-magnetic transition element site or on the s-p element site depends mainly on the chemical nature of the non-magnetic transition element rather than any other factor, e.g. the local moment μCo of the alloy.
