English abstract:
Electron energy-loss magnetic chiral dichroism (EMCD) allows for the quantification of magnetic properties
of materials at the nanometer scale. It is shown that with the support of simulations that help to
identify the optimal conditions for a successful experiment and upon implementing measurement
routines that effectively reduce the noise floor, EMCD measurements can be pushed towards quantitative
magnetic measurements even on individual nanoparticles. With this approach, the ratio of orbital to spin
magnetic moments for the Fe atoms in a single L10 ordered FePt nanoparticle is determined to be
ml/ms = 0.08 ± 0.02. This finding is in good quantitative agreement with the results of XMCD ensemble
measurements.
