摘要：
Initial magnetization and demagnetization data are reported for three types of isotropic Nd2Fe14B containing permanent magnet materials: annealed melt-spun Nd4Fe77B19, melt-spun Nd14Fe81B5, and sintered Nd16Fe78B6. A substantial magnetic interaction of the grains in Nd4Fe77B19 is indicated by the temperature dependence of the coercivity, by the remanence to saturation polarization ratio being 0.75, and by an unusual relation of remanence after magnetization to remanence after demagnetization.
