Magnetic Materials Group

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

Our research focuses on the study of magnetic, electronic, and structural properties of condensed matter systems using x-ray scattering and spectroscopy techniques. The group currently operates 4 beamlines at APS sectors 4 and 6, and is constructing a new beamline in sector 29.

Recent Research Highlights

A New Family of Quasicrystals

June 24, 2013

Scientists from the U.S. Department of Energy’s Ames Laboratory and Iowa State University have used the high energy x-rays available on beamline 6-ID-D, to confirm the structure of the only known magnetic rare earth icosahedral binary quasicrystals.

Beamlines

Vortex

4-ID-C: Soft X-ray Magnetic Spectroscopy

  This beamline 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 linear polarized light. This beamline is used for XCMD spectroscopy, resonant magnetic scattering, and X-PEEM imaging experiments.
Picuture

4-ID-D: Hard X-ray Magnetic Spectroscopy

  This beamline 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.
Sunset Yellow

6-ID-B: Resonant and In-Field Scattering

 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 experiments (collaboration only).
FeGa

6-ID-D: High Energy Scattering

 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.
IEX Window

29-ID: Intermediate Energy RSXS & ARPES

 Beamline 29-IDis an intermediate energy (200 -2000 eV) beamline designed for Resonant Soft X-ray Scattering (RSXS) and Angle ResolvedPhotoemission (ARPES) measurements. This beamline is currently in constructuon and is scheduled to begin operation in 2015.

All MMG beamlines offer time to outside users through the APS proposal system. If you are interesed in performing an experiment, please feel free to contact one or our staff.
