| 简介 |
The present invention comprises a main phase (10), a boundary phase (20) existing around the main phase (10), and an intermediate phase (30) interposed between the main phase (10) and the boundary phase (20). The entire composition is ((Ce(1-x)Lax)(1-y)R1y)pT(100-p-q-r)BqM1r· (R21-zM2z)s, wherein R1 and R2 are rare earth elements except Ce and La, T is at least one selected from Fe, Ni and Co, M1 is a microelement which does not have any influence on magnetic characteristics, and M2 is an alloying element making a melting point of R21-zM2z lower than melting point of R2.COPYRIGHT KIPO 2018 |
