Assume that the intergranular phase (IP) existing between adjacent grains is a weak magnetic phase, and could weaken or interrupt the intergrain exchange-coupling interaction (IECI). Using our proposed cubic-grain anisotropy model, we investigate the effects of IP's thickness d, and its anisotropy constant K1(0) on the coercivity of nanocrystalline Nd–Fe–B magnet. Calculation results indicate that the coercivity increases with increasing d, but decreases with increasing K1(0). When d=1.2nm and K1(0)=0.5K1(K1is the common anisotropy constant of the bulk Nd–Fe–B material), our calculated results are consistent with available experimental data.
