Abstract

The effects of the γ-ray irradiation on the magnetic properties of Nd-Fe-B permanent magnetic had been investigated. The magnetic flux loss of Nd-Fe-B magnet before and after irradiation was measured. Due to the accumulated high energy, γ-ray irradiation was used for the magnetic property loss of Nd- Fe-B magnet. The experimental results showed that the γ-ray irradiation affected the magnetic properties of permanent magnet by radiation dose at 0 kGy, 100 kGy, 500 kGy, and 700 kGy. Nd-Fe-B magnet has the decreased Ms and Hc by γ-ray irradiation. And the characterizations were done by XRD, FESEM images, and SQUID, etc.
