Abstract:Study on the temperature variation of domain revealed that the maindomains remain the same without change during heating, but the supplementary do-mains, such as the cone like reversal domains in the surface, would be changedboth in the size and shape, or even disappeared, while temperature is higher than240℃. Since the nucleation sites and the spontaneous orientation of nucleated do-main has some randomness, so the domain patterns should be changed every timeafter the thermal demagnetization higher than Curie point.
Key wordsdomain structure of NdFeB    thermal demagnetization    domain nucleation
