摘　　要：对纳米软磁合金Fe_(73)Cu_1Nb_(1.5)Mo_2Si_(12.5)B_(10)的制备态和各退火态的室温Mossbauer谱研究,发现非晶相的超精细内场存在高场和低场两部分,表明在析出的α-FeSi纳米晶粒和剩余的非晶相之间存在一个弱磁界面层,并且定量地研究了该界面层随退火温度的变化。此界面层对软磁纳米微晶的磁性质会产生重要的影响。Through the study on the Mossbauer spectrum of the nanocrystalline amorphous alloy Fe73Cu1Nb1.5Mo2Si12.5B10, we find that the hyperfine field can apparently be divided into two effective field; high field and low field. It is assumed that there is an interface with low magnetic field between the nanoparticle and the remained amorphous phase. We have also studied the variety of the interface with the varying anealing temperature and discussed the essential role it played in the magnetic property.
