Abstract:
Typical weak itinerant ferromagnetism has been found in Sc(Co1?xAlx)2, which a magnetism and higher Curie temperatures. Magnetic for X = 0.10. Lu(Co1?yAly)2 also shows ferromagnetism with much larger moments anad higher Curie temperatures. Magnetic and nonmagnetic Co atoms coexist in 0.06 < y < 0.12.
