Femtosecond dynamics of magnetic excitations from resonant inelastic x-ray scattering in CaCu2O3
Valentina Bisogni, Stefanos Kourtis, Claude Monney +10
Taking spinon excitations in the quantum antiferromagnet CaCu2O3 as an example, we demonstrate that femtosecond dynamics of magnetic excitations can be probed by direct resonant in…
Magnetic excitations in stripe-ordered LaBaCuO studied using resonant inelastic x-ray scattering
M. P. M. Dean, G. Dellea, M. Minola +10
The charge and spin correlations in LaBaCuO (LBCO 1/8) are studied using Cu edge resonant inelastic x-ray scattering (RIXS). The static charge order (…
Dispersive spin excitations in highly overdoped cuprates revealed by resonant inelastic x-ray scattering
M. Le Tacon, M. Minola, D. C. Peets +11
Using resonant inelastic x-ray scattering (RIXS) at the Cu -absorption edge, we have observed intense, dispersive spin excitations in highly overdoped TlBaCuO (s…
Persistence of magnetic excitations in La2-xSrxCuO4 from the undoped insulator to the heavily overdoped non-superconducting metal
M. P. M. Dean, G. Dellea, R. S. Springell +11
One of the most intensely studied scenarios of high-temperature superconductivity (HTS) postulates pairing by exchange of magnetic excitations [1]. Indeed, such excitations have be…
