Abstract
Magnetic measurements were performed on Y(FexAl1 - x)(3) compounds in the temperature range 5 to 800 K and external fields up to 7 T. Compou nds with x > 0.8 are ferromagnets. For x < 0.8 short-range order and f reezing effects of magnetic clusters originating from replacement of F e by Al are evidenced. The mean magnetic moments of iron clusters as w ell as their number are estimated. Above the Curie points, the thermal variations of magnetic susceptibilities obey Curie-Weiss type behavio r. The mean effective magnetic moments per iron atom are only weakly d ependent on composition.
