Abstract
The magnetic domain structure of Nd-Fe-B based crystalline grains is studied by transmission electron microscopy. The action of the objective lens magnetic field on the sample induces magnetization reversals. The experimental conditions of nucleation and saturation are compared with theoretical curves of magnetic energy of single domain particles.
