Vacancy-mediated fcc/bcc phase separation in Fe1-xNix ultrathin films
T. O. Mentes, N. Stojic, E. Vescovo +3
The phase separation occurring in Fe-Ni thin films near the Invar composition is studied by using high-resolution spectromicroscopy techniques and density functional theory calcula…
Fragmentation of magnetism in artificial kagome dipolar spin ice
Benjamin Canals, Ioan Augustin Chioar, Van-Dai Nguyen +7
Geometrical frustration in magnetic materials often gives rise to exotic, low-temperature states of matter, like the ones observed in spin ices. Here we report the imaging of the m…
Room temperature chiral magnetic skyrmion in ultrathin magnetic nanostructures
Olivier Boulle, Jan Vogel, Hongxin Yang +16
Magnetic skyrmions are chiral spin structures with a whirling configuration. Their topological properties, nanometer size and the fact that they can be moved by small current densi…
