英文摘要
We propose a new approach for the study of irradiation degradation. An Fe-Cr single crystal film with Cr concentration gradient prepared by electron beam deposition in UHV and irradiated by 2.4MeV Cu2+ ions at 475C. Irradiation effects on magnetization process were investigated using a Kerr microscope. Spike domains were observed at the boundary between irradiated and unirradiated regions, and the critical magnetic field where the spike domain disappears increased above the Cr concentration of 9%. This study shows the usefulness of combinatorial approach for the study of irradiation phenomena and demonstrates a feasibility of magnetic nondestructive evaluation of the embrittlement.
