In this article, the study of gadolinium material is focused on determining the constants and properties of the material, the analysis of substructures and the orientation of dipole moments. Research into material aspects provides important information on atomic-level sub-phenomena in the field of the main magnetocaloric phenomena for the magnetic refrigeration regenerator (AMR). The experimental study is mainly based on testing the magneto-caloric material with different magnetization equipment, developed to measure more precise and fine details, magnetic refrigerator, AMR prototype development and the like. The method used uses differential equations. For both cases, where the loads are relatively simple and for more complex cases, the method can be easily applied.

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
