  We propose a highly efficient atomically-resolved mode of electron magnetic
chiral dichroism. This method exploits the recently introduced orbital angular
momentum spectrometer to analyze the inelastically scattered electrons allowing
for simultaneous dispersion in both energy and angular momentum. The technique
offers several advantages over previous formulations of electron magnetic
chiral dichroism as it requires much simpler experimental conditions in terms
of specimen orientation and thickness. A novel simulation algorithm, based on
the multislice description of the beam propagation, is used to anticipate the
advantages of the new approach over current electron magnetic chiral dichroism
implementations. Numerical calculations confirm an increased magnetic signal to
noise ratio with in plane atomic resolution.
