"Is magnetic chiral dichroism feasible with electron vortices?";
Ultramicroscopy, 136 (2014), S. 81 - 85.



Kurzfassung englisch:
We discuss the feasibility of detecting magnetic transitions with focused electron vortex probes, suggested by selection rules for the magnetic quantum number. We theoretically estimate the dichroic signal strength in the L2;3 edge of the ferromagnetic d metals. It is shown that under realistic conditions, the dichroic signal is undetectable for nanoparticles larger than 1 nm. This is con rmed by a key experiment with nanometer sized vortices.
