Convergent-Beam EMCD: Benefits, Pitfalls, and Applications
Stefan Löffler, Walid Hetaba
Energy-loss magnetic chiral dichroism (EMCD) is a versatile method for studying magnetic properties on the nanoscale. However, the classical EMCD technique is notorious for its low…
Peculiar Rotation of Electron Vortex Beams
Thomas Schachinger, Stefan Löffler, Michael Stöger-Pollach +1
Standard electron optics predicts Larmor image rotation in the magnetic lens field of a TEM. Introducing the possibility to produce electron vortex beams with quantized orbital ang…
EMCD with an electron vortex filter: Limitations and possibilities
Thomas Schachinger, Stefan Löffler, Andreas Steiger-Thirsfeld +5
We discuss the feasibility of detecting spin polarized electronic transitions with a vortex filter. This approach does not rely on the principal condition of the standard energy lo…
