摘要:

SmCo5permanent magnets have been irradiated with 19.5 MeV protons at temperatures from about 300 to over 800 K. The results show that SmCo5magnets are very sensitive to irradiation at elevated temperatures. The relative magnetic flux loss has been calculated with a model based on the local heating caused by the incoming particle. The theoretical result agrees well with the experimental data.
