Preliminary Steps Toward a Full Magnetic Multislice Treatment of Momentum-Resolved Magnetic Inelastic Scattering Simulations

Le résumé fourni par la source

Understanding magnetic excitations in materials at nanometer resolution requires quantitative modeling of electron–magnetic moment interactions beyond conventional electrostatic multislice approaches. We present a forward dynamical electron scattering (FDES)[1] magnetic multislice [2,3] implementation that incorporates transverse magnetic scattering contributions [4] within a reciprocal-space formalism. In our approach, the electron wavefunction is propagated through magnetization-dependent phase gratings derived from spatially resolved magnetic textures, enabling the calculation of momentum-resolved diffuse scattering intensities relevant to magnetic inelastic scattering and electron energy-loss spectroscopy (EELS). The framework is implemented in a computational environment suitable for high-performance computing, allowing simulations of magnetically ordered materials at experimentally relevant beam energies and sample thicknesses. As a benchmark, we will present results for test materials to validate numerical stability, convergence behavior, and physically consistent magnetic contrast within the multislice formalism. These results serve as a controlled reference system for assessing the robustness of the implementation. Our work establishes a practical and extensible computational platform for quantitative studies of magnetic electron scattering and provides a foundation for systematic investigations of complex magnetic materials using dynamical electron propagation methods [5].
