摘要：

Fe-57 Mossbauer effect and magnetic susceptibility measurements have been performed on the new glassy alloys Al90Fe5Ce5, Al87Fe6.7C6.3, Al87Fe8.7Ce4.3, and Al87Fe9.3Ce3.7. It is found that Fe atoms are not magnetically ordered in the Fe-rich glasses down to 4.2 K. The disorder inherent to glasses is manifested in the distribution of the electric quadrupole splittings, which is shown to be well described by a Gaussian shape. The magnetic susceptibility of the alloys follows the Curie-Weiss law between 4.2 K and room temperature. The small effective magnetic moment values suggest mixed-valence behaviour.
