Abstract
To examine the possible roles for oxygen in the formation of the icosahedral and crystal approximant phases in Ti-TM-Si alloys (TM = V, Cr, Mn, Fe), the magnetic susceptibility was measured in the α(TiCrSiO) and α(TiMnSiO) 1 1 crystal approximant phases. The measured magnetic susceptibility, ξ, for α(TiCrSiO) is nearly independent of temperature over the range 6–300 K, showing no measurable Curie-Weiss component, The susceptibility of α(TiMnSiO) contains a small Curie-Weiss component corresponding to a local-moment ( j = 5 2 ) from only a small fraction (∼0.2%) of the Mn. The electronic density of states at the Fermi energy, N( E F ), estimated from the susceptibility contribution of the conduction electrons, changes monotonically with increasing oxygen in both alloys. This suggests that phase stabilization by oxygen does not arise from a Hume-Rothery-type mechanism in these alloys.
