The magnetic behavior of (Al,Ge)65CuMn quasicrystalline samples with ∼22 and 24 at.% Mn was investigated. High disordered magnetism was observed for these quaternary alloys. Short-range ferromagnetism in samples with high Ge and high Mn content along with the oscillatory magnetization were also observed. A double transition at T<75 K was observed in the sample with 0 at. % Ge. The results indicate that with the increase in the concentration of icosahedral phase in the alloys, magnetic disorder increases.
