      abstract     = {Two-dimensional (2D) van der Waals magnets have drawn
                      considerable attention in recent years triggered by the huge
                      interest in novel magnetism and spintronic devices. Magnetic
                      measurement of 2D van der Waals (vdW) magnets is crucial to
                      understand the physical origin of magnetism in 2D limits.
                      Therefore, advanced magnetic characterization techniques are
                      highly required. However, only a limited number of such
                      techniques are available due to the extremely small volume
                      of 2D vdW magnets. Here, we introduce the electron magnetic
                      chiral dichroism (EMCD) technique in transmission electron
                      microscope (TEM) to measure 2D vdW crystals. In comparison
                      with some other already-employed techniques in 2D magnets,
                      EMCD is able to quantitatively measure magnetic parameters
                      in three orthogonal directions at nanometer or even at
                      atomic scale. We then perform EMCD simulations on several
                      typical 2D vdW magnets with respect to the accelerating
                      voltage, the number of atomic layers and beam tilt under
                      zone axial orientation. The intensity and distribution of
                      EMCD signals in three orthogonal directions are given in the
                      diffraction plane, thereby providing an optimized design to
                      achieve EMCD measurements. Finally, we discuss the
                      signal-to-noise-ratio and required electron dose in order to
                      obtain a measurable EMCD signal for 2D vdW magnets. Our
                      results provide a feasibility analysis and guideline to
                      measure 2D vdW magnets in future experiments.},
