| 英文摘要 | The magnetic properties of commercial polycrystalline Nd2Fe14B (N50M, N45H, N40SH, N35EH) and Sm2Co17 (XG30/20, XG26/25, XG22/20) magnets at cryogenic temperatures were tested by using a comprehensive physical properties measurement system (PPMS). The results show that the spin tilt temperature T-st of Nd2Fe14B magnets is closely related to intrinsic coercivity H-ci, N50M and N45H with smaller H-ci show a residual magnetization jump at 235 K and 225 K, respectively. For Sm2Co17 magnets, in 50-300 K, with temperature decreasing, residual magnetization M-rc shows a nearly linear increase, while in 10-50 K, M-rc has little change. The research results provide a reference for cryogenic undulators and other high-precision cryogenic devices. |
