We have measured the degree of magnetization of VFe alloys up to 33 % at. Fe with particular emphasis on the concentrations where ferromagnetism appears (22 %). The values of the Curie constant and of the saturation magnetization can be interpreted in terms of giant moments of about 20 µB. The ordering temperature Tc and the paramagnetic Curie temperature θp were measured. The variation with the concentration of iron of the high field susceptibility indicates the occurrence of exchange enhancement effects, as observed in systems with isolated impurities
