• The behavior of 3d electrons in binary Nd–Fe alloys with different Nd content from 7 to 13at.% has been studied by using positron coincidence Doppler broadening techniques. It has been found that the 3d electron signal in Nd2Fe17 alloy is relatively high as compared with other alloys. In Fe-rich Nd2Fe17 alloys, as the content of Fe increasing, the phase boundaries between α-Fe and Nd2Fe17 phases will increase, which gives rise to the decrease in the probability of positron annihilation with 3d electrons. In Nd-rich Nd2Fe17 alloys, with the decrease of Fe content, the d–d interactions are weakened, and the probability of positron annihilation with 3d electrons will decrease. The coercivity JHc and remanence Jr of the Nd–Fe alloy increase with the d–d interaction.
