Title: Multicomponent fluctuation spectrum at the quantum critical point in CeCu _6-xAg _x

Abstract

Quantum critical points (QCPs) are widely accepted as a source of a diverse set of collective quantum phases of matter. The basic nature of a QCP is manifested in the critical fluctuation spectrum which in turn is determined by the adjacent phases and associated order parameters. Here we show that the critical fluctuation spectrum of CeCu _5.8Ag _0.2 can not be explained by fluctuations associated with a single wave vector. Interestingly, when the critical fluctuations at wave vectors corresponding to the incommensurate antiferromagnetic order adjacent to the QCP are separated they are found to be three dimensional and to obey the scaling behavior expected for long wavelength fluctuations near an itinerant antiferromagnetic QCP. Without this separation, E/T scaling with a fractional exponent is observed. Together these results demonstrate that a multicomponent fluctuation spectrum is a previously unexplored route to obtaining E/T scaling at a QCP.

Interplay between unconventional superconductivity and heavy-fermion quantum criticality: CeCu ₂Si ₂ versus YbRh ₂Si ₂

Journal Article Smidman, M. ; Stockert, O. ; Arndt, J. ; ... - Philosophical Magazine (2003, Print)

In this paper the low-temperature properties of two isostructural canonical heavy-fermion compounds are contrasted with regards to the interplay between antiferromagnetic (AF) quantum criticality and superconductivity. For CeCu ₂Si ₂, fully-gapped d-wave superconductivity forms in the vicinity of an itinerant three-dimensional heavy-fermion spin-density-wave (SDW) quantum critical point (QCP). Inelastic neutron scattering results highlight that both quantum critical SDW fluctuations as well as Mott-type fluctuations of local magnetic moments contribute to the formation of Cooper pairs in CeCu ₂Si ₂. In YbRh ₂Si ₂, superconductivity appears to be suppressed at T ≳10 mK by AF order ( T _N = 70more »« less

Structural and magnetic phase transitions in CeCu _6-xT _x (T = Ag,Pd)

Journal Article Poudel, Lekhanath N. ; De la cruz, Clarina ; Payzant, E. Andrew ; ... - Physical Review. B, Condensed Matter and Materials Physics

The structural and the magnetic properties of CeCu _6-xAg _x (0 ≤ x ≤ 0.85) and CeCu _6-xPd _x (0 ≤ x ≤ 0.4) have been studied using neutron diffraction, resonant ultrasound spectroscopy (RUS), x-ray diffraction measurements, and first principles calculations. The structural and magnetic phase diagrams of CeCu _6-xAg _x and CeCu _6-xPd _x as a function of Ag/Pd composition are reported. The end member, CeCu ₆, undergoes a structural phase transition from an orthorhombic ( Pnma) to a monoclinic (P2 ₁/c) phase at 240 K. In CeCu _6-xAg _x, the structural phase transition temperature (T _s) decreases linearlymore »« less

Magnetic correlations and quantum criticality in the insulating antiferromagnetic, insulating spin liquid, renormalized Fermi liquid, and metallic antiferromagnetic phases of the Mott system V{sub 2}O{sub 3}

Journal Article Bao, W. ; Broholm, C. ; Aeppli, G. ; ... - Physical Review, B: Condensed Matter

Magnetic correlations in all four phases of pure and doped vanadium sesquioxide (V{sub 2}O{sub 3}) have been examined by magnetic thermal-neutron scattering. Specifically, we have studied the antiferromagnetic and paramagnetic phases of metallic V{sub 2{minus}y}O{sub 3}, the antiferromagnetic insulating and paramagnetic metallic phases of stoichiometric V{sub 2}O{sub 3}, and the antiferromagnetic and paramagnetic phases of insulating V{sub 1.944}Cr{sub 0.056}O{sub 3}. While the antiferromagnetic insulator can be accounted for by a localized Heisenberg spin model, the long-range order in the antiferromagnetic metal is an incommensurate spin-density wave, resulting from a Fermi surface nesting instability.

Quantum Critical Scaling and the Origin of Non-fermi-liquid Behavior in Sc _1-xU _xPd ₃

Journal Article Wilson, Stephen D. ; Dai, Pengcheng ; Adroja, D. T. ; ... - Physical Review Letters

We used inelastic neutron scattering to study magnetic excitations of Sc{sub 1-x}U{sub x}Pd{sub 3} for U concentrations (x=0.25, 0.35) near the spin glass quantum critical point (QCP). The excitations are spatially incoherent, broad in energy (E=variant Planck's over 2{pi}{omega}), and follow {omega}/T scaling at all wave vectors investigated. Since similar {omega}/T scaling has been observed for UCu{sub 5-x}Pd{sub x} and CeCu{sub 6-x}Au{sub x} near the antiferromagnetic QCP, we argue that the observed non-Fermi-liquid behavior in these f-electron materials arises from the critical phenomena near a T=0 K phase transition, irrespective of the nature of the transition.
