| Abstract: | The present situation and the key factors of applied temperature are summarized on high temperature permanent magnets. The development status is introduced and the effect of component on applied temperature is analyzed on Sm(Co,Cu, Fe, Zr)_z permanent magnets, then the mechanism of coercivity is generalized. At last the research situation on Sm(Co, Cu, Fe, Zr)_z permanent magnets is discussed. |
