Quantum Critical Matter and Phase Transitions in Rare Earths and Actinides
2016, Handbook on the Physics and Chemistry of Rare EarthsCitation Excerpt :Note that even at zero doping x = 0 there is a rather large residual resistivity! The SDW, as detected by neutron scattering (Schröder et al., 1994), is a most subtle form of magnetism and the tiny x-disorder is essential to tune it. The mysterious “Kondo hybridization” between the Ce 4f electrons and the conduction electrons compensate the moments, thereby diminish the Ruderman–Kittel–Kasuya–Yosida (RKKY) interaction resulting in this small moment itinerant SDW.

2002, Physica B: Condensed MatterCitation Excerpt :This material is also on the brink of magnetism, as revealed both by early inelastic neutron scattering measurements [6] as well as later studies [7] of the alloy series CeCu6−xAux, showing that for x>0.15, the ground state is antiferromagnetic. At the quantum critical point [8], the Sommerfeld constant diverges logarithmically with decreasing T, and the resistivity as well as bulk magnetic susceptibility do not show the quadratic rise and T-independent Pauli term, respectively, associated with Fermi liquids, including CeCu6 itself. Instead, ρ∼T while χb displays a singular rise as T approaches zero.
