Triplet excitations in the frustrated spin ladder LiCuO(SO)
Ornella Vaccarelli, Andreas Honecker, Paola Giura +4
Magnetic excitations of the recently discovered frustrated spin-1/2 two-leg ladder system LiCuO(SO) are investigated using inelastic neutron scattering, magnetic su…
The crystal structure of Rb2Ti2O5
R. Federicci, B. Baptiste, F. Finocchi +9
Recent results have demonstrated an exceptionally high dielectric constant in the range 200 K-330 K in a crystalline tianium oxide : Rb2Ti2O5. In this article, the possibility of a…
Observation of low energy dispersive modes in un- derdoped (La, Nd) 2--x Sr x CuO 4
Matteo D 'Astuto, Sylvain Denis, Jeff Graf +10
We find excitations lower in energy than known phonon modes in underdoped LaSrCuO (x=0.08), with both inelastic X-Ray scattering (IXS) and inelastic neutron…
Electron localization and possible phase separation in the absence of a charge density wave in single-phase 1T-VS
A. Gauzzi, A. Sellam, G. Rousse +12
We report on a systematic study of the structural, magnetic and transport properties of high-purity 1T-VS powder samples prepared under high pressure. The results differ notabl…
Phonon anomalies and lattice dynamics in superconducting oxychlorides CaCuOCl
Matteo D'Astuto, Ikuya Yamada, Paola Giura +6
We present a comprehensive study of the phonon dispersion in an underdoped, superconducting CaCuOCl crystal. We interpret the results using lattice dynamical calcul…
Temperature evolution of infrared- and Raman-active phonons in graphite
P. Giura, N. Bonini, G. Creff +3
We perform a comparative experimental and theoretical study of the temperature dependence up to 700 K of the frequency and linewidths of the graphite E1u and E2g optical phonons (~…
