Query: muSR in Ce_{1-x}La_xAl_3: anisotropic Kondo effect?   Zero-field muSR experiments in the heavy-fermion alloys Ce_{1-x}La_xAl_3, x =
0 and 0.2, examine a recent proposal that the system exhibits a strong
anisotropic Kondo effect. We resolve a damped oscillatory component for both La
concentrations, indicative of disordered antiferromagnetism. For x = 0.2 the
oscillation frequency decreases smoothly with increasing temperature, and
vanishes at the specific heat anomaly temperature T* \approx 2.2 K. Our results
are consistent with the view that T* is due to a magnetic transition rather
than anisotropic Kondo behavior.
