My apologies, the location changed. Due to unfinished renovation
business in the lecture room the seminar will be held at IF on the
2nd floor in the meeting room. Please keep in mind the space limits
there before deciding on online/live mode of participation.<br>
<br>
Best regards,<br>
<br>

<div style="text-align: justify;" data-mce-style="text-align:
justify;" align="justify">Resonant inelastic X-ray scattering
(RIXS) is a photon-in photon-out technique in which the system
is resonantly excited at an absorption edge and the scattered
photons are measured in order to probe the energy and momentum
transfer of the intrinsic excitations, such as electronic,
magnetic or of the lattice. This spectroscopy has been subject
of a remarkable progress in the last decades for its
capability of gaining information of fundamental interest for
correlated systems. <br>
At the SEXTANTS beamline of the synchrotron SOLEIL, we perform
RIXS experiments in the soft X-ray regime. After a short
presentation of the technique, I will highlight some of the
main experimental results we recently obtained. One example is
represented by the work on La1-xSrxVO3, a canonical example of
correlated system exhibiting a filling control metal-insulator
transition, as well as orbital and antiferromagnetic orderings
at low temperature. I will show how low-doping (x=0.1) affects
the electronic structure primarily on the O sites, at odds
with a simple Mott-Hubbard picture, and how RIXS can measure
orbital excitations and their behavior with temperature. I
will discuss how these results can be only partially
understood by a local model based on crystal field theory
calculations. <br>
Finally, I will describe the capabilities of the novel MAGELEC
sample environment, which was conceived for performing RIXS
experiments under electric and magnetic fields in a
temperature range from 400 K down to 18 K. MAGELEC consists of
sample holder equipped with 12 electrical contacts, which is
combined with a compact quadrupolar magnet delivering a
rotatable magnetic field up to 0.45 T. Thanks to the
particular design of the electromagnet, the whole scattering
plane is available for magnetic circular and linear dichroism
RIXS experiments. I will show how this unique sample
environment, accessible for external users since February
2020, opens new perspectives at the SEXTANTS beamline thanks
to the possibility to tackle several kinds of open questions
in the field of transition metal compounds beyond the accuracy
obtained by the widely used X-ray magnetic circular dichroism
and in operando conditions. <br>
