AbstractFor spin reorientation (SRT), the applications of sintering NdFeB permanent magnets are limited at low temperature. The sintering PrFeB permanent magnet (PM) presents no SRT and shows excellent magnetic properties at low temperature. The magnetic properties of bulk polycrystalline sintering Pr1-xNdxFeB (x - 0 and 0.8 correspond to P42II and N50M respectively) are studied in this paper. The results show that magnetic properties and stability of N50M are better than those of 42H at room temperature. With the decrease of temperature, the parameters of B-r, H-cb, and H-ci of P42H present a nearly linear increasing trend; Br and Hcb of N50M first increase and then decline, Hci presents an increasing trend. At 77 K, Br, H-ci, and J(r) of P42H are increased by 18.7%, 308%, and 17.1% respectively over than those at 300 K; at 120 K, Br, Hci, and Jr of N50M are increased by about 16.19%, 245%, and 12.6% respectively over than those at 300 K. The magnetic properties of P42H are better than those of N50M at low temperature. The sintering PrFeB is the preferred PM in various low temperature devices.
