Hard magnetic property and δm (H) plot for sintered NdFeB magnet
Journal of Magnetism and Magnetic Materials 208(2000)239-243，-0001，（）：
The hard magnetic properties and the interactions between the grains for sintered Nd16 Fe73 Co5 B6 magnets are investigated by using δM (H) plot technique. The results show that the δM (H) plot of NdFeB sintered magnet can explain the effects of the microstructure (size, shape and orientation of the grains) and the intergrain interactions on the hard magnetic properties of the magnet. However, the value of δM (H) is positive when the applied field is not strong enough, which means that the common δM (H) plot theory is not completely consistent with the sintered NdFeB magnet.
