A thermodynarnically stable quasicrystalline phase with a decagonal structure was found to be formed in an Al40Mn25Fe15Ge20- The single phase was prepared by conventional solidification, followed by annealing for 100 h at 1050 K and then water quenching. The decagonal phase was identified to be the 6 layer (1.2 nm) Al4Mn-type decagonal structure. This alloy exhibits magnetization of 6.3 emu/g in an applied field of 10 kOe at 40 K.
