Title: Magnetic field study of Ce{sub 0.8}La{sub 0.2}Al{sub 3}

Abstract

A partial substitution of La for Ce in CeAl{sub 3} leads to large anomalies in the low temperature specific heat, presumably of magnetic origin, and results in a strong reduction of {gamma}. Magnetic fields up to 14 T have little effect on the temperature position of the anomaly in Ce{sub 0.8}La{sub 0.2}Al{sub 3} but attenuate its magnitude. Specific heats of Ce{sub 0.8}La{sub 0.2}Al{sub 3} and CeAl{sub 3} approach each other in large fields of order 14 T. Magnetic fields increase {gamma} of Ce{sub 0.8}La{sub 0.2}Al{sub 3}.
