N2 - Formation criteria and magnetic properties of rapidly solidified Al-Ge-TM (TM=Cr, Fe and Co) alloys were examined. The phase changes from amorphous, icosahedral, and decagonal, to approximant crystalline, corresponding to TM as Cr (Ge rich), Cr, Fe and Co, respectively, in the rapidly solidified Al-Ge-TM alloys. Thermomagnetic curves indicate that for the systematically variation of the magnetic ordered phases, Al40Ge40Cr20 amorphous, Al60Ge20Cr20 icosahedral, Al50Ge20Fe30 decagonal and Al60Ge10Co30 approximant crystalline alloys were identified to be of ferromagnetism, mictomagnetism, Curie-Weiss paramagnetism and Pauli paramagnetism, respectively.
