Claus M. Schneider

Claus M. Schneider is a Professor at the Faculty of Physics, University of Duisburg-Essen, and director of the Peter Grünberg Institute (PGI-6) at Forschungszentrum Jülich. His research focuses on the electronic structure of quantum materials, particularly correlated electron systems, using advanced photoelectron spectroscopy techniques.

• Current affiliations: University of Duisburg-Essen, Forschungszentrum Jülich
• Key experimental facilities: Synchrotron radiation sources DELTA (Dortmund), BESSY (Berlin), ELETTRA (Trieste)

His work investigates the fundamental connections between electronic structure and physical properties like superconductivity, magnetism, and giant magnetoresistance. Techniques include high-resolution photoelectron spectroscopy with laboratory sources and synchrotron-based nanospectroscopy, enabling energy, spatial, and temporal resolution at atomic scales.

Recent research highlights include the discovery of tunable orbital angular momentum in crystals and the production of the first 2D semimetal with spin-selective conductivity. His group operates specialized equipment such as a microwave-excited rare gas lamp system for photoemission and a hemispherical analyzer with spin-polarization analysis capabilities.

The group's experimental infrastructure spans laboratory-based ARPES systems and synchrotron beamlines optimized for angle- and spin-resolved studies of magnetic multilayers, interfaces, and topological materials. All experiments are conducted under ultra-high vacuum conditions, with integrated surface preparation and characterization tools.
