The magnetic hyperfine field B-hf for Cd in the Heusler alloy Pd2MnSn at th
e site of chemically introduced Ag has been investigated by PAC following t
he beta (-) decay of Ag-111. Sign and temperature dependence of B-hf have b
een determined. Comparison of the result B-hf (T = 0) = +8.0(1) T with earl
ier data and ab-initio band structure calculations leads to the conclusion
that the Ag activity has been incorporated at the Mn site.
