Pressure dependence of phonon modes across the tetragonal to collapsed tetragonal phase transition in CaFe2As2
R. Mittal, R. Heid, A. Bosak +14
The pressure dependence of a large number of phonon modes in CaFe2As2 with energies covering the full range of the phonon spectrum has been studied using inelastic x-ray and neutro…
Inelastic X-ray Scattering Study of superconducting SmFeAs(OF) Single Crystals: Evidence for Strong Momentum-Dependent Doping-Induced Renormalizations of Optical Phonons
M. Le Tacon, T. R. Forrest, Ch. Rüegg +10
We report inelastic x-ray scattering experiments on the lattice dynamics in SmFeAsO and superconducting SmFeAsOF single crystals. Particular attention was paid to…
Experimental Proof of a Magnetic Coulomb Phase
Tom Fennell, P. P. Deen, A. R. Wildes +6
Spin ice materials are magnetic substances in which the spin directions map onto hydrogen positions in water ice. Recently this analogy has been elevated to an electromagnetic equi…
Field-induced soft-mode quantum phase transition in LaSrCuO
J. Chang, N. B. Christensen, Ch. Niedermayer +13
Inelastic neutron-scattering experiments on the high-temperature superconductor LaSrCuO reveal a magnetic excitation gap that decreases continuously u…
