| Abstract | Introduction Magnetite (Fe3O4) has been widely studied due to its predicted spin polarization of -100%[1]. On cooling through ~122K (Tv), it undergoes a first-order phase transition, named Verwey transition[2]. Co-doped Fe3O4 has attracted particular attention because of its enhanced structural anisotropy and magnetic anisotropy. The magnetocrystalline anisotropy constant of Fe2CoO4 is about 1.8×10 J/m[3]. It is reported that Co ions mainly substitutes the Fe ions in magnetite[4]. Co doping changes magnetic properties, destroys Verwey transition and reduces megnetoresistance[5]. So far, there is still lack of evidence on the valence band structure of Codoped Fe3O4, which is significant to understand its physical and chemical properties. |
