| Abstract: | 99Ru,61Ni,57Fe and119Sn Mössbauer spectroscopic studies were made on ternary intermetallic compounds containing ruthenium, RuxY3?xZ (Y=Fe, Ni; Z=Si, Sn). In the system of RuxFe3?xSi, two different hyperfine magnetic fields were observed at the99Ru nuclei (H hfRu]) in the range ofx≤1.0 and the magnitude of eachH hfRu] was found to decrease with an increase in the ruthenium concentrationx. Both the99Ru and119Sn Mössbauer spectra of Ru2FeSn could be analyzed with two sets of magnetically split lines. The61Ni Mössbauer spectra of Ru2NiSn were obtained at 5 and 77 K. |
