Abstract Al90Ni2Y8 and Al84Ni8Y8 alloy ribbons were produced by melt–spinning, the structural characterization of the as–quenched samples was performed by XRD, the thermal stability of the as–quenched alloys was characterized using a differential scanning calorimeter (DSC), the magnetism of both Al90Ni2Y8 and Al84Ni8Y8 alloys fully amorphous and partially crystallized were investigated using a superconducting quantum interference device (SQUID). The results show that the magnetism of thamorphous Al90Ni2Y8 and Al84Ni8Y8alloys are diamagnetism, and the alloys are magnetized more easily with higher Ni content. When the magnetic field reaches 0.5 T, the specific magnetizations of Al90Ni2Y8 and Al84Ni8Y8alloy are −0.083 and −0.091 Am2/kg, and the magnetisabilities are −1.66×10−5 and −1.2×10−5, respectively. The magnetism of alloys remains unchanged after partially crystallized, but the absolute value of specific magnetization is correspondingly increased. After partially crystallization, the absolute value of specific magnetization of the Al90Ni2Y8 alloy increases from 0.083 Am2/kg to 0.231 Am2/kg, and that of the Al84Ni8Y8 alloy increases from 0.091 Am2/kg to 0.163 Am2/kg corresponding to a magnetic field of 0.5 T, and also the absolute value of magnetisability reaches to 4.62×10−5 and 3.26×10−5, respectiely, which is attributed to the Ni and Y elemental build–up around the nanometer sized pure Al crystals after partially crystallizatin.
