The magnetic susceptibility and thermal expansion have been measured for the pseudobinary Y(Mn1-xAlx)2 system. The thermal expansion anomaly, which was observed for YMn2, rapidly decreases with increasing Al content and disappears around x=0.10. Furthermore, the susceptibility, being almost temperature independent for YMn2, becomes of the Curie-Weiss type as the Al content increases. These results strongly Y(M1-xAlx)2 is a typical system which exhibits a transition from an itinerant electron to a local moment character.
