本文通过对Co-Fe-γFe_2O_3磁粉的包复过程进行研究,讨论了外延钴铁氧体包复层中Fe~(2+)离子的作用及对磁性能影响的机理,并发现包复溶液的[OH]~(1-)浓度通过改变外延钴铁氧体包复层中的Fe~(2+)离子量而起作用.文中对钴铁氧体的包复增加了γ-Fe_2O_3矫顽力的机理也进行了探索.
In this paper, the process of Co-Fe-γFe_2O_3 magnetic particle cladding process was studied, the effect of Fe ~ (2+) ions in the extended cobalt ferrite cladding layer and the mechanism of its effect on magnetic properties were discussed. The concentration of [OH] 1- (1) plays a role by changing the amount of Fe ~ (2+) ions in the epitaxial cobalt ferrite cladding layer. The coercivity of γ-Fe_2O_3 The mechanism is also explored.
