| Outline of Final Research Achievements |
We successfully developed Barkhausen noise (BHN) measurement system with three magnetic pole. It generated the uniform rotating magnetic field. To discuss about magnetic domain wall movement in stress, in-situ observation system for magnetic domain wall movement was also developed. Moreover, parameters, such as mmagnetostriction and texture of the test piece were also measured. From obtained results, stress behavior of BHN for quantitative evaluation was discussed.
