Orbital excitations in titanates
C. Ulrich, A. Gössling, M. Grüninger +6
Raman scattering is used to observe pronounced electronic excitations around 230 meV - well above the two-phonon range - in the Mott insulators LaTiO and YTiO. Based on the…
Manifestation of the magnetic resonance mode in the nodal quasiparticle lifetime in superconducting cuprates
A. A. Kordyuk, S. V. Borisenko, A. Koitzsch +9
Studying the nodal quasiparticles in superconducting cuprates by photoemission with highly improved momentum resolution, we show that a new "kink" feature in the scattering rate is…
The resonant magnetic mode: a common feature of high- superconductors
Ph. Bourges, B. Keimer, S. Pailhès +3
Inelastic neutron scattering experiments in high- cuprates have evidenced a new magnetic excitation present in the superconducting state. In particular, recent experiments on…
Magnetic resonance peak and nonmagnetic impurities
Y. Sidis, P. Bourges, B. Keimer +6
Nonmagnetic Zn impurities are known to strongly suppress superconductivity. We review their effects on the spin excitation spectrum in , as investigated by inel…
