By combining the results of muon spin relaxation and inelastic neutron scattering in the heavy fermion compounds Ce1-xLaxAl3 (0.0<or=x<or=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… 
Magnetic correlations in the CeAl3 heavy-fermion system
The inelastic neutron scattering spectra of the CeAl3 heavy-fermion system are measured over a wide range of momentum transfers with the aim of determining the type of ion-ion magnetic correlations.
Inhomogeneous level splitting in Pr 2-x BixRu2O7.
It is shown that a continuous distribution of splittings of the non-Kramers Pr3+ ground-state doublet such as might result from various types of lattice strain can account for all the data.
Crystal-field effects in the mixed-valence compounds Yb2M3Ga9 (M= Rh, Ir)
Magnetic susceptibility, heat capacity, and electrical resistivity measurements have been carried out on single crystals of the intermediate valence compounds Yb2 Rh3 Ga9 and Yb2 Ir3 Ga9. These
Hastatic order in the heavy-fermion compound URu2Si2
It is shown that the recent observation of Ising quasiparticles in URu2Si2 results from a spinor order parameter that breaks double time-reversal symmetry, mixing states of integer and half-integer spin.
Cure to the Landau–Pomeranchuk and associated long-wavelength Fermi-surface instabilities on the lattice
The cure to the l = 1 Landau–Pomeranchuk instabilities in translationally invariant fermions is shown to be a state with an anisotropic gap at the Fermi surface. For higher l and for fermions on a
Hastatic Order in URu2Si2
The development of collective long-range order via phase transitions occurs by the spontaneous breaking of fundamental symmetries. Magnetism is a consequence of broken time-reversal symmetry while
Numerical renormalization group method for quantum impurity systems
In the early 1970s, Wilson developed the concept of a fully nonperturbative renormalization group transformation. When applied to the Kondo problem, this numerical renormalization group (NRG) method
Colloquium: Hidden order, superconductivity, and magnetism: The unsolved case of URu 2 Si 2
This Colloquium reviews the 25 year quest to understand the continuous (second-order), mean-field-like phase transition occurring at 17.5 K in ${\mathrm{URu}}_{2}{\mathrm{Si}}_{2}$. About ten years
