By Time Differential Perturbed Angular Correlation measurements, the field values on {sup 111}Cd at the 3 different sites of the Heusler alloy Pd{sub 2}MnSn have been obtained. Using these experimental values, the Conduction Electron Polarization as a function of distance between the probe and the magnetic moment has been calculated. The trends of the magnetic fields on Cd, In and Sn probes in Pd{sub 2}MnSn have been presented. Attempts to force {sup 57}Fe-probe to enter different sites in the Heusler alloys Pd{sub 2}MnSn, Ni{sub 2}MnSn and Ni{sub 2}MnSn had partial success as indicated by the field values obtained by the Moessbauer Technique. The comparison of our {sup 57}Fe Moessbauer results to {sup 55}Mn-NMR results, leads to tentative conclusion that the Fe probe does not behave in the same manner as the Mn probe.
