N2 - In order to access the spin glass-like feature in the CoSi 1-xAlx alloys, we measured the DC magnetization under zero-field-cooled (ZFC) and field-cooled (FC) procedures for CoSi 0.85Al0.15 and CoSi0.70Al0.30 with various external magnetic fields. It has been found that the magnetic susceptibility and the irreversibility between ZFC and FC measurements in both compounds are very sensitive to the applied field. We associated the formation of the spin glass state with the Si/Al disorder in these materials.
