Article Description

Magnetic susceptibility and Al27 nuclear magnetic resonance data are reported for the non-Fermi-liquid (NFL) alloys U1-xLaxPd2Al3,x=0.8,0.9, and 1.0. Ten percent doping of the lanthanum sites with uranium impurities shifts the resonance frequency of Al27 nuclei near the U ions sufficiently such that satellite lines are resolved from the bulk line. The extra broadening of these satellite lines in U0.1La0.9Pd2Al3 is evidence for inhomogeneity in the magnetic susceptibility, and agrees with the NFL Kondo disorder model (KDM) and the Griffiths-McCoy phase model (GMPM) theories. However, the resulting distributions of characteristic energies do not extend down to zero, where uncompensated spins at finite temperatures would give rise to NFL behavior. This is evidence that the distribution of energies is not broad enough to be the cause of NFL behavior as described by the KDM and GMPM. © 2005 The American Physical Society.
