| Abstract: | New complex metallic alloys of the Taylor phase Al3Mn with 8, 10 and 12% Fe substitution are investigated by 57Fe M?ssbauer spectroscopy. Two groups of subspectra, with different hyperfine parameters are obtained, and are allocated to Fe sites with only Al nearest neighbors and Fe sites with both Al and Mn in the first shell. No difference between crystalline and quasicrystalline compounds is found indicating that long range periodicity plays a minor role. |
