By performing La doping on the Ce sites we have demonstrated that the heavy-fermion ground state in CeAl{sub 3} is extremely unstable toward local-moment antiferromagnetism. Profound changes in the low-temperature specific heat are already seen at the 1% doping level. We believe that this sensitivity to structural/chemical modifications is responsible for a large number of the mutually contradictory experimental results reported for CeAl{sub 3}. Further, we propose that the weak {ital C}/{ital T} structure observed for some CeAl{sub 3} samples near 0.4 K has a magnetic origin.
