Popis: CoSm permanent magnets are characterized by high coercivity, which is due to the formation of a cellular nanostructure. For the understanding and optimization of these magnets, the evolution and morphology of the cellular structure need to be analyzed, most commonly by transmission electron microscopy (TEM). Meanwhile, high-resolution scanning electron microscopy (SEM) is enabling the visualization and large-scale imaging of the nanostructure while requiring relatively little preparation effort, combined with easy sample handling. Different preparation techniques will be used to visualize different microstructural constituents, enabling the analysis of their morphologies and fractions.
