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…
Phonon lineshapes in the vortex state of the phonon-mediated superconductor YNiBC
F. Weber, L. Pintschovius, K. Hradil +1
We present an inelastic neutron scattering study of phonon lineshapes in the vortex state of the type-II superconductor YNiBC. In a previous study [Phys. Rev. Lett. \textbf…
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…
Phonon dispersion and low energy anomaly in CaC
Matteo D'Astuto, Matteo Calandra, N. Bendiab +10
We report measurements of phonon dispersion in CaC using inelastic X-ray and neutron scattering. We find good overall agreement, particularly in the 50 meV energy region, betwe…
Magnetic field effect on the superconducting magnetic gap of Nd{1.85}Ce{0.15}CuO4
E. M. Motoyama, P. K. Mang, D. Petitgrand +4
Inelastic neutron scattering measurements on the archetypical electron-doped material Nd{1.85}Ce{0.15}CuO4 up to high relative magnetic field strength, H/Hc2 ~ 50%, reveal a simple…
Superexchange coupling and spin susceptibility spectral weight in undoped monolayer cuprates
P. Bourges, H. Casalta, A. S. Ivanov +1
A systematic inelastic neutron scattering study of the superexchange interaction in three different undoped monolayer cuprates (La_2CuO_4, Nd_2CuO_4 and Pr_2CuO_4) has been perform…
