| Research Abstract |
To investigate the mechanism on the demagnetization of permanent magnets caused by radiations (mainly neutrons) from accelerators, the degrees of demagnetization were measured for neutrons of various energies produced by a nuclear reactor and accelerators. The microscopic studies on the changes of electromagnetic structures inside the magnet caused by radiations are also performed by using radioactive nuclei as probes. Additionally, developments on the unstable nuclei as probes and the techniques on radioactive beam are performed.
