Aw. Carbonari et al., MAGNETIC HYPERFINE FIELDS IN THE HEUSLER ALLOYS CO2YZ (Y=SC, TI, HF, V, NB, Z = AL, GA, SI, GE, SN), Hyperfine interactions, 80(1-4), 1993, pp. 971-976
The magnetic hyperfine field acting on Ta at the non-magnetic transiti
on 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 in Ta-181 following the
beta- decay of Hf-181. An important conclusion is that the reduced mhf
either on the non-magnetic transition element site or on the s-p elem
ent site depends mainly on the chemical nature of the non-magnetic tra
nsition element rather than any other factor, e.g. the local moment mu
(Co) of the alloy.
