For x≈20, the Co-Er alloys show X-raydiffraction patterns in which the dominant phase can be indexed successfully withicosahedral lattice vectors. The quasicrystal Co-Er alloys are strongly magneticshowing many characteristics of sperimagnetism observed in amorphous films ofsimilar composition. The experimental results show typical magnetic properties ofthe icosahedral phase lying between those of the amorphous phase and the crystal-line phase of similar compositions. The quasicrystalline-to-crystalline transforma-tion was observed in the temperature range 385 to 630℃. The observations fuelthe assertion made by Steinhardt et al., that the icosahedral phase is a new typeof structural formula of materials.
