Magnetic properties of Al-Si-Mn and Al-Mn quasicrystals and amorphous films
Abstract
Unlike the orthorhombic phase, the icosahedral phase of Al86Mn14 exhibits a local magnetic moment. The effective moment of icosahedral-phase Al-Mn and Al-Si-Mn alloys increases with Mn concentration up to a maximum of (1.5+/-0.5μB). The amorphous and icosahedral phases of Al-Si-Mn have similar magnetic properties for Si concentrations <~6 at. %, and the moments seem to order in a spin-glass state. For Si concentrations >~30 at. %, amorphous Al-Si-Mn orders ferromagnetically.
