Magnetic Materials

The Magnetic Material 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

Superconductivity with Stripes

October 18, 2013

Scientists have used high pressure x-ray spectroscopy and diffraction on beamline 4-ID-D to probe the relationship between stripe ordering and superconductivity. This work is an important step in understanding high-Tc superconductivity and eventually achieving practical room-temperature superconductors.

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