| Outline of Final Research Achievements |
We tried to improve the sensitivity of a magnetic field sensor using thin-filmed ferromagnetic material and to miniaturize the sensor element. The effects of the anisotropy direction on the sensor behaviors were investigated, and the mechanism of discontinuous jump which is observed on the elements having inclined magnetic domain was clarified. The influence of demagnetizing effect was also investigated; the optimum shape was obtained and then the element having 30 micro-meters long were demonstrated. For the applications of nondestructive testing, the behaviors of transformations into ferromagnetic on SUS304 steel and Inconel600 alloy were clarified. The obtained results indicate a potential of local nondestructive testing using magnetism.
