“…The sample growth and characterization methods have been reported previously [35][36][37]. The RIXS measurements were performed with the ERIXS spectrometer at the beam line ID32 of the European Synchrotron Radiation Facility (ESRF) in Grenoble, France [38]. The RIXS spectra were collected at 20K with π incident polarization (parallel to the scattering plane) to maximize the single-magnon signal [2,39].…”

Using Cu-L3 edge resonant inelastic x-ray scattering (RIXS) we measured the dispersion and damping of spin excitations (magnons and paramagnons) in the high-Tc superconductor (Bi,Pb)2(Sr,La)2CuO 6+δ (Bi2201), for a large doping range across the phase diagram (0.03 p 0.21). Selected measurements with full polarization analysis unambiguously demonstrate the spinflip character of these excitations, even in the overdoped sample. We find that the undamped frequencies increase slightly with doping for all accessible momenta, while the damping grows rapidly, faster in the (0,0)→(0.5,0.5) nodal direction than in the (0,0)→(0.5,0) antinodal direction. We compare the experimental results to numerically exact determinant quantum Monte Carlo (DQMC) calculations that provide the spin dynamical structure factor S(Q, ω) of the three-band Hubbard model. The theory reproduces well the momentum and doping dependence of the dispersions and spectral weights of magnetic excitations. These results provide compelling evidence that paramagnons, although increasingly damped, persist across the superconducting dome of the cuprate phase diagram; this implies that long range antiferromagnetic correlations are quickly washed away, while short range magnetic interactions are little affected by doping.

“…To date, XFEL-based RIXS tends to lag behind synchrotron experiments in terms of energy and momentum resolution. Many of the technical developments implemented at synchrotrons [17,56] can potentially be employed at XFELs provided further practical complications, such as limited experimental floor space, compatibility with other experiments, finite beam stability, can be avoided or overcome. In many cases shorter spectrometers ( 2 m compared to ∼ 15 m at synchrotrons) are more practical at XFELs.…”

Many remarkable properties of quantum materials emerge from states with intricate coupling between the charge, spin and orbital degrees of freedom. Ultrafast photo-excitations of these materials hold great promise for understanding and controlling the properties of these states. Here we introduce time-resolved resonant inelastic X-ray scattering (tr-RIXS) as a means of measuring the charge, spin and orbital excitations out of equilibrium. These excitations encode the correlations and interactions that determine the detailed properties of the states generated. After outlining the basic principles and instrumentation of tr-RIXS, we review our first observations of transient antiferromagnetic correlations in quasi two dimensions in a photo-excited Mott insulator and present possible future routes of this fast-developing technique. The increasing number of X-ray free electron laser facilities not only enables tackling long-standing fundamental scientific problems, but also promises to unleash novel inelastic X-ray scattering spectroscopies.

“…For a systematic and quantitative study of the different ordering phenomena in RNiO 3 , high-quality RIXS spectra with high-resolution are necessary. We therefore performed the RIXS experiments at the ID32 beamline of the European Synchrotron Radiation Facility using the ERIXS spectrometer 45 . As a compromise between reasonable acquisition time and sufficient resolving power, the combined instrumental energy resolution was set to ≈ 50 meV full width at half maximum (FWHM).…”

We used high-resolution resonant inelastic x-ray scattering (RIXS) at the Ni L3 edge to simultaneously investigate high-energy interband transitions characteristic of Ni-O bond ordering and low-energy collective excitations of the Ni spins in the rare-earth nickelates RNiO3 (R = Nd, Pr, La) with pseudocubic perovskite structure. With the support of calculations based on a doublecluster model we quantify bond order (BO) amplitudes for different thin films and heterostructures and discriminate short-range BO fluctuations from long-range static order. Moreover we investigate magnetic order and exchange interactions in spatially confined RNiO3 slabs by probing dispersive magnon excitations. While our study of superlattices (SLs) grown in the (001) direction of the perovskite structure reveals a robust non-collinear spin spiral magnetic order with dispersive magnon excitations that are essentially unperturbed by BO modulations and spatial confinement, we find magnons with flat dispersions and strongly reduced energies in SLs grown in the (111)pc direction that exhibit collinear magnetic order. These results give insight into the interplay of different collective ordering phenomena in a prototypical 3d transition metal oxide and establish RIXS as a powerful tool to quantitatively study several order parameters and the corresponding collective excitations within one experiment.
