Abstract

The Mössbauer spectra of the icosahedrally coordinated phases in the alloys Ti₅₈Mn_34.5Fe_2.5Si₅, Ti₆₁Mn₃₂Fe₅Si₂, Ti₆₁Mn₂₂Fe₁₅Si₂, and Ti_63-yMn₂₇Fe₁₀Si_y, where y = 2.5, 5.0, and 7.5, respectively, have been measured at 78 K. The resulting spectra are best fit with a distribution of quadrupole interactions which are linearly correlated with the isomer shift. The average quadrupole splitting, the shape, and the width of the distribution function indicate that the Mackay icosahedron is the principal building block in these materials.
