Magnetic Materials Group

The Magnetic Materials Group is part of the X-ray Science Division (XSD) at the Advanced Photon Source.

Our research focuses on the study of magnetic properties of condensed matter systems using x-ray scattering and spectroscopy techniques. The group operates 3 beamlines in APS sectors 4 and 6.

Different Roads Toward Quantum Criticality

The study of magnetic phase diagrams is essential to understanding the organizing principles of correlated electrons, as well as understanding the way in which physical parameters determine material properties.

Beamlines

  •   Beamline 4-ID-C operates in the soft x-ray energy spectrum (500 - 2700 eV) and uses an electromagnetic helical undulator to provide circularly polarized x-rays of either helicity and both vertically and horizontally linar polarized light. This beamline is used for XCMD spectroscopy, resonant magnetic scattering, and X-PEEM imaging experiments.

  •   Beamline 4-ID-D is designed for hard x-ray operation (2.5 - 50 keV).  This beamline is equipped with phase retarding optics and is capable of manipulating and analyzing the polarization of incident and/or scattered x-ray beams for magnetic circular dichroism (XMCD) and magnetic scattering experiments.

  •   Beamline 6-ID is currently transitioning to full APS operation. This beamline has both a general purpose diffraction station (4 - 35 keV) and a side-bouce high-energy station ( 35 - 120 keV).

Currently, 4-ID offers 80% and 6-ID offers 50% of their beam time to outside users through the APS general user proposal system. If you are interesed in performing an experiment, please feel free to contact one or our staff.
