Königssystems Explores Magnetic and Structural Properties of La₀.₅Sr₀.₅CoO₂.₈₅ at ESRF with Advanced EXAFS Analysis

Königssystems Team Conducts Experiment at ESRF (Grenoble)

From May 8 to 11, 2025, the Königssystems team participated in an experiment at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, as part of a project led by Dr. Alexandre Ivanov (Institut Laue-Langevin). The experiment was carried out at beamline BM23 and focused on a temperature-dependent EXAFS (Extended X-ray Absorption Fine Structure) study of local structural distortions in multivalent states of La₀.₅Sr₀.₅CoO₂.₈₅.

The goal of the experiment was to analyze local and long-range structural distortions under varying temperatures and material modifications induced by a pulsed magnetic field (up to 140 T). The results are expected to provide deeper insights into the nature of spin-state transitions between Co³⁺ and Co⁴⁺, as well as the influence of anisotropic CoO growth and oxygen distribution on the magnetic and structural properties of the material.

This experiment contributes to fundamental research in solid-state physics and the development of novel functional materials.
