| Outline of Final Research Achievements |
We developed an analysis software of three-dimensional (3D) internal structures of the sintered permanent magnets extracting the two-dimensional (2D) small-angle neutron scattering (SANS) pattern. The 3D structures cannot be directly extracted from the SANS pattern because of so-called phase problem. Therefore, a 3D structure is modeled by several structural parameters, and then the model is fourier transformed into the SANS pattern. This pattern is compared with a real pattern obtained by SANS measurements. The first version of the software was released though it will be further improved in future.
