Coupling between spin and orbital degrees of freedom in KCuF3.
TL;DR: Evidence is given for a strong coupling between orbital and spin degrees of freedom and the interplay between magnetic and orbital order parameters is revealed by the temperature dependence of the intensity of orbital Bragg peaks.

Resonant soft x-ray scattering investigation of orbital and magnetic ordering in La0.5Sr1.5MnO4
Stuart Wilkins,Stuart Wilkins,N. Stojić,T. A. W. Beale,Nadia Binggeli,C. W. M. Castleton,C. W. M. Castleton,Peter Bencok,D. Prabhakaran,Andrew T. Boothroyd,Peter D. Hatton,M. Altarelli,M. Altarelli +12 more
TL;DR: In this paper, resonant x-ray scattering data of the orbital and magnetic ordering at low temperatures at the Mn L-2,L-3 edges in La 0.5Sr1.5MnO4.
Mn L 2,3 edge resonant x-ray scattering in manganites: Influence of the magnetic state
TL;DR: In this paper, the dependence of the resonant orbital-order and magnetic scattering spectra on the spin configuration was analyzed and the Hannon-Trammel formula was implemented inside the framework of atomic multiplet calculations in a crystal field.

Evidence of Orbital Ordering in Jahn-Teller Undistorted LaSr$_{2}$Mn$_{2}$O$_{7}$
Stuart Wilkins,N. Stojić,T. A. W. Beale,Nadia Binggeli,Peter Bencok,Stefan Stanescu,John F. Mitchell,Peter Abbamonte,Peter D. Hatton,M. Altarelli +9 more
TL;DR: In this paper, the authors used soft x-ray diffraction to probe the temperature dependent orbital and magnetic structure of a low-temperature A-type antiferromagnetic phase.

TL;DR: In this article, the results of resonant x-ray scattering experiments on KCuF3 were presented, and the electronic structure of the kinematic structure was determined by means of ab initio local spin density approximation with on-site Coulomb interaction (LSDA+U) calculations.
