Welcome to Magnetic Materials

The newly formed Magnetic Materials Group concentrates on emergent phenomena in quantum materials using the capabilities of beamlines I06, I10, I16, B16 and I21. The research encompasses a variety of challenges and opportunities at the frontiers of condensed matter physics and materials science ranging from topological states of matter, superconductivity, spintronics, two-dimensional systems, skyrmions and multiferroics.

The key insights made by researchers exploit the high sensitivity of polarised X-ray spectroscopy, microscopy and scattering available across the beamlines. For instance, polarised soft X-rays combined with the PhotoEmission Electron Microscope (PEEM) on the Nanoscience beamline (I06) have visualised the domain dynamics underpinning antiferromagnetic spintronics while the resonant soft X-ray scattering on the BLADE: X-ray Dichroism and Scattering beamline (I10) has been used to understand the topological properties of skyrmions. On the Materials and Magnetism beamline (I16), interference effects in hard X-ray scattering have led to a deeper understanding of long-range magnetic ordering in canted antiferromagnets. The Inelastic X-ray Scattering beamline (I21) is in a commissioning phase, but has had already performed ground breaking experiments measuring orbital excitations, magnon dispersion and electron-phonon coupling in several highly-correlated systems. In this inaugural contribution to the annual highlights we present research from our user community that uniquely demonstrates how polarised X-ray science can uncover dramatic changes in the magnetic properties of materials from subtle changes to the geometric and electronic structure.

Energy: 4 - 45 keV

I21 Inelastic X-ray Scattering

Operational in optimisation mode

I21 will be a dedicated Resonant Inelastic X-ray Scattering (RIXS) beamline that will provide a highly monochromatised, focused and tunable X-ray beam onto materials, while detecting and energy-analysing scattered X-rays using a spatially-resolved two-dimensional detector.
