摘要：
The effect of thermal stabilization (pre-baking at 142degreesC) on the sensitivity of neodymium-iron-boron (Nd2Fe14B) magnets to irradiation was studied. Thermally stabilized magnets showed higher resistance to irradiation with 2.0 GeV electrons: their demagnetization curves decrease linearly with respect to the number of electrons, and with a demagnetization rate remarkably smaller than that of the unbaked magnets.
