چکیده
|
During the synthesis of the γ-fenanoparticles via the chemically induced transition method,cu(i) modification has been attempted by adding cucl/naoh to the treatment solution. the experimental results showed that,under the condition of a naoh content equal to 0.04 moles,when the content of cucl is as low as 1.25 × 10 - 3 or 2.50 × 10 - 3 moles,the products are single γ-fecu(i)feofeclmiddot;6h composite nanoparticles,whereas when the content of cucl is higher,5 × 10 - 2 moles,the product is a mixture consisting of γ-fecu(i)feofeclmiddot;6h nanoparticles and cu(ii)(oh)cl nanoparticles. for the γ-fecu(i)feofeclmiddot;6h composite nanoparticles,the cu(i)feointerface layer is not thick enough to form one unit cell,but it can modify the formation of a feclmiddot;6h surface layer and the effective magnetization of the γ-fecore. © 2015 hong mao et al.
