Abstract
A low-temperature magnetoresistance of CeAl3 is discussed using a model in which the potential scattering at Ce sites leads to a virtual bound state beow epsilon F and the scattering on the 4f magnetic fluctuations gives rise to a narrow Kondo resonance at epsilon F. Positive magnetoresistance is predicted in the zero-temperature limit while it decreases with the increase of temperature and changes sign at T approximately=TK/2 pi . The minimum magnetoresistance is reached at about T-TK/2.Keywords
