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

Probing Spin Liquids with a New Pulsed-Magnet System

August 26, 2010

Pulsed magnetic fields have recently been used on beamline 4-ID-D to study magnetoelastic effects in the rare-earth pyrochlore terbium titanate spin-liquid compound. A change is structural symmetry is observed for fields above 25 Tesla.

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.

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

  This beamline operates at hard x-ray energies (2.5 - 40 keV), and provides polarized x-rays using phase retarding optics. It is used for magnetic circular dichroism (XMCD) and magnetic scattering experiments.

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

 Beamline 6-ID-B,C operates in the 4-35 keV energy range. Station B station houses a general purpose psi-diffractometer for resonant scattering. Station C is dedicated to scattering experiments in high magnetic fields.

6-ID-D: High Energy Scattering

 Beamline 6-ID-D is the high-energy( 50 - 130 keV) scattering station on 6-ID. This beamline uses a prototype superconducting undulator as its x-ray source and can leverage harmonic radiation from a planar undulator in the same straight section for additional flux. This station is used primarily for materials characterization using area detectors.

29-ID: Intermediate Energy RSXS & ARPES

 Beamline 29-ID is an intermediate energy (200 -2000 eV) beamline designed for Resonant Soft X-ray Scattering (RSXS) and Angle Resolved Photoemission (ARPES) measurements. This beamline is currently in commissioning and is scheduled to begin user operation in 2016.

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.
