The Electronic Structure, Magnetism and Dynamics (EMD) group supports studies of excited states of matter ranging from meV to tens of keV by means of X-ray spectroscopy. The introduction to the group's chapter in the annual ESRF Highlights gives an overview of some recent accomplishments.
The principle areas of study are the chemical, electronic, magnetic and dynamic properties of materials. These properties are closely related to the functionality of the material, be it chemical, magnetic or electrical. The fields of research include materials science, correlated materials, magnetism, superconductivity, catalysis, coordination chemistry, environmental science, geochemistry, geophysics, etc.
The group supports a range of specialized spectroscopic techniques, which fall under the following general headings:
- X-ray absorption spectroscopy
- Resonant Inelastic X-ray scattering, X-ray emission spectroscopy
- (Non-resonant) Inelastic X-ray scattering
- X-ray magnetic circular dichroism
The group performs meaurements of matter under extreme conditions and provides an infrastructure for in-situ studies. A detailed list is available on the techniques page.
The ESRF’s mission includes interacting with and supporting European industry. Synchrotron X-rays permit analysis of industrial products under real conditions of manufacture and use, often in real time. Some examples of applications at this group's beamlines include:
- Determination of sulphur speciation in oils.
- Oxidation state of Fe in glasses.
- In situ studies of chemical processes and changes in functional materials.
Some representative publications from previous industrial use indicate the range of capabilities.
The individuals listed above and the staff of the Business Development Office are available to help industrial researchers identify appropriate resources at the ESRF.
In-house research runs in parallel to beamline operation, helping us to develop and refine techniques while investigating diverse scientific areas. Areas of research are listed on our in-house research page.
From time to time, staff and users have connections with the following beamlines, which are operated by Collaborative Research Groups (CRGs):
- BM1B Swiss-Norwegian Beamlines (X-ray absorption & diffraction)
- BM2 D2AM (materials science)
- BM8 GILDA (general purpose diffraction/absorption
- BM20 ROBL (radiochemistry & ion beam physics)
- BM25A SPLINE (X-ray absorption & diffraction)
- BM26 DUBBLE (small-angle scattering & interface diffraction)
- BM28 XMAS (magnetic scattering)
- BM30B FAME (absorption spect./material and environ. sciences)
- BM32 IF (interfaces)
