Hyperfine Field Distributions

The 119Sn hyperfine field in the Heusler alloys Ir1.07Mn1.07Sn0.86, PtMnSn, Ni2MnSn, Co2MnSn, and Pd2MnSn has been measured using the Mössbauer effect. Hyperfine field distributions were obtained from the Mössbauer spectra via the Fourier expansion method of Window. The spectra of Ni2MnSn, Co2MnSn, and Pd2MnSn showed a well-defined value of the hyperfine field. This indicates a well-ordered structure and is consistent with previous neutron diffraction and NMR measurements on these alloys. The Ir1.07Mn1.07Sn0.86 and PtMnSn spectra, on the other hand, showed a wide distribution of fields, indicating a considerable amount of disorder. The extent and type of disorder, as indicated by X-ray diffraction measurements, are also considered.

Conduction Electron Density

Sn hyperfine fields were measured using Mössbauer spectroscopy in the Heusler alloys Rh2MnZ (Z = Ge, Sn). The measurements yielded values of −48 and +31 kOe at 77 K for Sn in Rh2MnGe and Rh2MnSn, respectively. These values showed that in these alloys the Sn hyperfine field decreases with increasing conduction electron density. These results are compared with those obtained for Sn hyperfine fields in X2MnZ and Co2YZ Heusler alloys and are discussed in terms of theoretical predictions.
