Quantum critical behavior in Ce(FeRu)Ge: the full story
Wouter Montfrooij, Tom Heitmann, Yiming Qiu +7
Systems with embedded magnetic ions that exhibit a competition between magnetic order and disorder down to absolute zero can display unusual low temperature behaviors of the resist…
Identification of the low-energy excitations in a quantum critical system
Tom Heitmann, Jagat Lamsal, Shannon Watson +4
We have identified low-energy magnetic excitations in a doped quantum critical system by means of polarized neutron scattering experiments. The presence of these excitations could…
Resonance Damping of the THz-frequency Transverse Acoustic Phonon in the Relaxor Ferroelectric KTa1-xNbxO3
J. Toulouse, E. Iolin, B. Hennion +2
The damping () of the transverse acoustic (TA) phonon in single crystals of the relaxor with x=0.15-0.17 was studied by means of high resolution inelastic c…
Neutron, electron and X-ray scattering investigation of Cr1-xVx near Quantum Criticality
D. A. Sokolov, M. C. Aronson, L. Wu +8
The weakness of electron-electron correlations in the itinerant antiferromagnet Cr doped with V has long been considered the reason that neither new collective electronic states or…
Friedel-like Oscillations from Interstitial Iron in Superconducting Fe1+yTe0.62Se0.38
V. Thampy, J. Kang, J. A. Rodriguez-Rivera +14
Using polarized and unpolarized neutron scattering we show that interstitial Fe in superconducting Fe_{1+y}Te_{1-x}Se_x induces a magnetic Friedel-like oscillation that diffracts a…
A new scattering mechanism of acoustic phonons in relaxor ferroelectrics: the case of KTa_{1-x}Nb_xO_3
J. Toulouse, E. Iolin, B. Hennion +3
The complex interaction between transverse acoustic (TA) phonon, transverse optic (TO) phonon and polar nano-domains (PND) in the relaxor ferroelectric KTa1-xNbxO3 (KTN) is studied…
