Three states of ${\mathrm{Al}}_{65}$${\mathrm{Cu}}_{20}$${\mathrm{Fe}}_{15}$: Amorphous, crystalline, and quasicrystalline

${\mathrm{Al}}_{65}$ ${\mathrm{Cu}}_{20}$ ${\mathrm{Fe}}_{15}$, prepared by magnetron sputtering and subsequently annealed, has been observed in three distinct states: amorphous, metastable crystalline, and quasicrystalline. The structural and physical properties of ${\mathrm{Al}}_{65}$ ${\mathrm{Cu}}_{20}$ ${\mathrm{Fe}}_{15}$ have been studied in these three different atomic arrangements. Distinct values of magnetic moment, resistivity, and hyperfine interactions at the Fe sites have been measured for the three states.
