摘要: A method is presented to compute the electron-optical phase shift for a magnetized polyhedral nanoparticle, with either uniform magnetization or closure domain (vortex state). The relies on an analytical expression shape amplitude, combined reciprocal-space description of magnetic vector potential. model used construct two building blocks from which more complex structures can be generated. Phase computations are also five Platonic and 13 Archimedean solids. Fresnel Foucault imaging mode simulations range particle shapes microscope conditions.
