Mobile orbitons in CaCuO: crucial role of the Hund's exchange
Roberto Fumagalli, Jonas Heverhagen, Davide Betto +9
We investigate the Cu edge resonant inelastic x-ray scattering (RIXS) spectra of a quasi-1D antiferromagnet CaCuO. In addition to the magnetic excitations, which are…
Block-spiral magnetism: An exotic type of frustrated order
J. Herbrych, J. Heverhagen, G. Alvarez +3
Competing interactions in Quantum Materials induce novel states of matter such as frustrated magnets, an extensive field of research both from the theoretical and experimental pers…
Novel Magnetic Block States in Low-Dimensional Iron-Based Superconductors
J. Herbrych, J. Heverhagen, N. D. Patel +4
Inelastic neutron scattering recently confirmed the theoretical prediction of a -magnetic state along the legs of quasi-one-dimensional (quasi…
Spinon-orbiton repulsion and attraction mediated by Hund's rule
Jonas Heverhagen, Maria Daghofer
We study the impact of Hund's-rule coupling on orbital excitations, as e.g. measured in inelastic resonant x-ray scattering. We find that the interpretation in terms of spin-orbit…
