Combining X-ray absorption spectroscopy with a multifunctional probe to decipher first-order phase transitions — •Benedikt Eggert¹, Alex Aubert², Shingo Yamamoto³, Ana Kurtanidze^3,4, Thomas Herrmannsdörfer³, Oliver Gutfleisch², Kurt Kummer⁵, Nick Brookes⁵, Jochen Wosnitza^3,4, Katharina Ollefs⁶, Konstantin Skokov², and Heiko Wende¹ — ¹University Duisburg-Essen — ²TU Darmstadt — ³HZDR, HLD-EMFL — ⁴TU Dresden — ⁵ESRF — ⁶KIP, University Heidelberg

Here, we present a new instrumental setup designed for the investigation of magnetostructural phase transition, installed within the high field magnet at beamline ID32 of the European Synchrotron Radiation Facility in Grenoble, France. With these newly established setups, we can perform dichroic X-ray absorption spectroscopy, while accessing other subsystems via bulk probes (e.g., lattice expansion or change in electrical resistivity) within a temperature range from 4 K to 650 K in the soft X-ray regime.

Here, we will show first experimental results from La(Fe,Si)13 during the field and temperature-induced magnetostructural phase transition showcasing some of the possibilities.

Funding by the BMFTR under Grant BMBF-Projekt05K2022, and the Deutsche Forschungsgemeinschaft via CRC/TRR 270 HoMMage (Project-ID 405553726) is gratefully acknowledged. We thank the ESRF for the allocation of beamtime.
