Localized and delocalized Ti 3d carriers in LaAlO3/SrTiO3 superlattices revealed by resonant inelastic x-ray scattering

Thorsten Schmitt, Joël Mesot

The important source of interface conductivity in LaAlO3/SrTiO3 heterostructures, the Ti 3d carriers, is probed with resonant inelastic x-ray scattering at the Ti 2p(3/2) edge of epitaxially grown superlattices. We reveal unambiguously the generation of bo ...

Measurement of Magnetic Excitations in the Two-Dimensional Antiferromagnetic Sr2CuO2Cl2 Insulator Using Resonant X-Ray Scattering: Evidence for Extended Interactions

Henrik Moodysson Rønnow, Marco Grioni, Helmuth Berger, Thorsten Schmitt, Marco Guarise, Bastien Dalla Piazza, Ping-Hui Lin, Peng Xu, Dirk Van der Marel

We measured the momentum dependence of magnetic excitations in the model spin-1/2 2D antiferromagnetic insulator Sr2CuO2Cl2 (SCOC). We identify a single-spin-wave feature and a multimagnon continuum, with different polarization dependences. The spin waves ...

High-resolution soft X-ray beamline ADRESS at the Swiss Light Source for resonant inelastic X-ray scattering and angle-resolved photoelectron spectroscopies

Marco Grioni, Thorsten Schmitt, Xiao Wang

The concepts and technical realisation of the high-resolution soft X-ray beamline ADRESS operating in the energy range from 300 to 1600 eV and intended for resonant inelastic X-ray scattering (R1XS) and angle-resolved photoelectron spectioscopy (ARPES) are ...

Evidence for core-hole-mediated inelastic x-ray scattering from metallic Fe1.087Te

Henrik Moodysson Rønnow, Marco Grioni, Marco Guarise, Thorsten Schmitt, Ping-Hui Lin, Dirk Van der Marel

We present a detailed analysis of resonant inelastic x-ray scattering from Fe1.087Te with unprecedented energy resolution. In contrast to the sharp peaks typically seen in insulating systems at the transition-metal L-3 edge, we observe spectra which show d ...

Crystal field and low energy excitations measured by high resolution RIXS at the L-3 edge of Cu, Ni and Mn

Marco Grioni, Helmuth Berger, Thorsten Schmitt, Xiaoqiang Wang, Xiao Wang

Resonant inelastic x-ray scattering in the soft x-ray regime has been profiting much from technical advances that have lowered considerably the instrumental linewidth. At the ADRESS beam line of the Swiss Light Source the SAXES spectrometer can be used to ...

Observation of Two Nondispersive Magnetic Excitations in NiO by Resonant Inelastic Soft-X-Ray Scattering

Marco Grioni, Helmuth Berger, Thorsten Schmitt, Xiaoqiang Wang, Xiao Wang

We present high resolution (Delta E=120 meV) resonant inelastic x-ray scattering data measured at the Ni L-3 edge (2p(3/2)-> 3d) on the paradigmatic antiferromagnetic oxide NiO. Spectra reveal clear signatures of magnetic excitations at similar to 95 and s ...

Collective Magnetic Excitations in the Spin Ladder Sr14Cu24O41 Measured Using High-Resolution Resonant Inelastic X-Ray Scattering

Henrik Moodysson Rønnow, Thorsten Schmitt, Joël Mesot, Xi Wang

We investigate magnetic excitations in the spin-ladder compound Sr14Cu24O41 using high-resolution Cu L-3 edge resonant inelastic x-ray scattering (RIXS). Our findings demonstrate that RIXS couples to two-triplon collective excitations. In contrast to inela ...

SAXES, a high resolution spectrometer for resonant x-ray emission in the 400-1600 eV energy range

Marco Grioni, Xiaoqiang Wang, Thorsten Schmitt, Xiao Wang

We present a 5 m long spectrometer for soft x rays to be used at a synchrotron radiation beamline for resonant x-ray emission spectroscopy and resonant inelastic x-ray scattering in the 400-1600 eV energy range. It is based on a variable line spacing spher ...
