Schematic of membrane flexure and domain modification under strain

Designing antiferromagnetic domains by stretching membranes in STXM

Researchers from an international collaboration between the United Kingdom and Switzerland have performed imaging of an antiferromagnetic iron oxide membrane using soft X-ray microscopy. By stretching the membranes using a gas cell, the team investigated the modification of domain structures under strain.

3D image of a magnetic skyrmion

Skyrmion topology quantified in 3D

Researchers from an international collaboration between the United States of America and Switzerland have performed three-dimensional magnetic imaging of a magnetic skyrmion using soft X-ray laminography. This allowed for the investigation, in three dimensions, of the topological profile of the magnetic skyrmions.

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
