A familiar method to enhance coercivity of neodymium-iron-boron sintered magnet is to diffuse heavy rare earth element into the main phase from the magnet surface through the boundary phase.
In this report, the influence of non-uniform coercivity distribution by diffusing Dy and Tb as heavy rare earth element in thermal demagnetization is studied and the simulation results by JMAG are reported.
