我们描述了对涂有油酸且裸露的细碎（直径约 100 Å）CoFe2O4 颗粒的 X 射线和偏振中子粉末衍射研究。 (4,0,0)线形状和中子翻转比表明，由于表面活性剂的存在，铁氧体中可能会产生约 25 Å 厚的无序且磁异常的壳层。
We describe an X-ray and polarized neutron powder diffraction study of finely divided (diameter ≈ 100 Å) CoFe2O4particles coated with oleic acid and naked. (4,0,0) line shapes, and neutron flipping ratio indicates that a disordered and magnetically anomalous shell approximately 25 Å thick may be induced in the ferrite by the presence of the surfactant.
