Magnetic correlations and the Anisotropic Kondo Effect in Ce1-xLaxAl3

Magnetic correlations and the Anisotropic Kondo Effect in Ce1-xLaxAl3
Magnetic correlations and the Anisotropic Kondo Effect in Ce1-xLaxAl3
By combining the results of muon spin relaxation and inelastic neutron scattering in the heavy fermion compounds Ce1-xLaxAl3 (0.0 <=x <=0.2), we show that static magnetic correlations are suppressed above a characteristic temperature, T*, by electronic dissipation rather than by thermal disorder. Below T* an energy gap opens in the single-ion magnetic response in agreement with the predictions of the anisotropic Kondo model. Scaling arguments suggest that similar behavior may underlie the ‘‘hidden order’’ in URu2Si2.

Abstract

By combining the results of muon spin relaxation and inelastic neutron scattering in the heavy fermion compounds Ce1-xLaxAl3 (0.0 <=x <=0.2), we show that static magnetic correlations are suppressed above a characteristic temperature, T*, by electronic dissipation rather than by thermal disorder. Below T* an energy gap opens in the single-ion magnetic response in agreement with the predictions of the anisotropic Kondo model. Scaling arguments suggest that similar behavior may underlie the ‘‘hidden order’’ in URu2Si2.
