| Research Abstract |
The behavior of hysteresis loop, impedance measurement using magnetic single-yoke and displacement measurement by laser technique were clarified experimentally, when magnetically gap exists between a specimen and a magnetic yoke. Consequently, the potential of non-contact and nondestructive evaluation method using magnetic measurement was performed. Then, the developed method was applied to evaluation of neutron irradiated materials, and relation between irradiation damage and magnetic properties was investigated.
