We present a parameter-free method of extraction of the electron magnetic circular dichroism spectra from energy-filtered diffraction patterns measured on a crystalline specimen. The method is based on a multivariate curve resolution technique. The main advantage of the proposed method is that it allows extraction of the magnetic signal regardless of the symmetry and orientation of the crystal, as long as there is a sufficiently strong magnetic component of the signal in the diffraction plane. This method essentially overcomes difficulties in extraction of the EMCD signal caused by complexity of dynamical diffraction effects.
► New method of extraction of EMCD signal using statistical methods (multivariate curve resolution).
► EMCD can be extracted quantitatively regardless of symmetry of crystal or its orientation.
► First principles simulation of EFDIF datacube, including dynamical diffraction effects
