Current Highlights and News
Three-dimensional magnonics
Researchers from an international collaboration between Switzerland, Italy, and Germany have performed the first time-resolved imaging at sub-ns timescales of the three-dimensional propagation dynamics of a spinwave in a synthetic antiferromagnetic nanostructured device, opening up the possibility to investigate magnon dynamics in complex three-dimensional geometries.
Spatially reconfigurable topological textures in freestanding antiferromagnetic nanomembranes
Researchers from the University of Oxford have imaged, through the use of the soft X-ray microscopy capabilities at the Swiss Light Source, spatially reconfigurable antiferromagnetic states in topologically rich free-standing nanomembranes
TEY-STXM confirms homogeneous doping of nanoparticles for non-fullerene organic solar cells
One of the challenges in modern research on the fabrication of non-fullerene acceptor based organic solar cells is the availability of very efficient hole transport layers (HTLs). A new approach that avoids mutual solubility issues is to deposit the HTL from a suspension of doped organic nanoparticles. Surface-sensitive TEY-STXM measurements at the PolLux beamline characterised the homogeneity of the dopant in the nanoparticles and develop efficient nanoparticle HTL materials for organic solar cells.
