English abstract:
The coupling between Angstrom-sized electron probes and spin polarised
electronic transitions shows that the inelastically scattered probe is in a
mixed state containing electron vortices with non-zero orbital angular
momentum. These electrons create an asymmetric intensity distribution in energy
filtered diffraction patterns, giving access to maps of the magnetic moments
with atomic resolution. A feasibility experiment shows evidence of the
predicted effect. Potential applications are column-by-column maps of magnetic
ordering, and the creation of Angstrom-sized free electrons with orbital
angular momentum by inelastic scattering in a thin ferromagnetic foil.
