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 4 beamlines in APS sectors 4 and 6.

Chirality-Hands

A New Spin on Inducing Chirality in Pre-biological Molecules

October 23, 2008

Researchers using beamline 4-ID-C have demonstrated that a previously unconsidered mechanism can play a role in chiral-selective chemistry: namely low-energy spin-polarized secondary electrons, produced by irradiation of a magnetic substrate.

Beamlines

  •   Beamline 4-ID-C operates in the soft x-ray energy spectrum (500 - 2700 eV) using 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 operates at hard x-ray energies (2.5 - 50 keV), and provides polarized x-rays using phase retarding optics. It is used for magnetic circular dichroism (XMCD) and magnetic scattering experiments.

  •  Beamline 6-ID-B,C is the primary beamline on 6-ID. It provides 4-35 keV x-rays into the B station for general purpose (psi-diffractometer) and in-field (4-Tesla) scattering experiments, and C station for UHV in-situ growth expeirments.

  •   Beamline 6-ID-D is the high-energy( 50 - 130 keV) scattering station on 6-ID. This beamline operates prarisitically ~50% of the time with the primary beamline (undulator source is shared) . This station is used primarily for materials characterization using area detectors.

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