摘要:

 多晶材料的性能深受其晶粒群形貌及結(jié)構(gòu)參數(shù)如晶粒取向分布函數(shù)的影響，這種影響在具有各向異性晶體結(jié)構(gòu)的多晶薄膜以及多晶薄膜的電學(xué)性能方面表現(xiàn)得尤為突出，比較有代表性的例子就是Fe3O4磁性薄膜。作為一種典型的半金屬，F(xiàn)e3O4由于在費米面處理論上100%的自旋極化率以及適中的電阻率，成為半導(dǎo)體自旋電子學(xué)領(lǐng)域的熱門材料。針對Fe3O4薄膜制備中經(jīng)常出現(xiàn)的（111）取向生長模式，介紹了Fe3O4薄膜中織構(gòu)結(jié)構(gòu)相關(guān)的自旋輸運及磁化動力學(xué)（磁各向異性）性能的研究進展。

Abstract:

 The properties of polycrystalline materials are strongly determined by structural and morphological parameters of the grain population such as the orientation distribution function. This effect becomes especially important if the material exhibits an anisotropic crystal structure or in the case of electronic properties of thin films, such as a typical material system—magnetite Fe3O4 films. As a typical half metallic material, Fe3O4 magnetic films have attracted much attention in semiconductor spintronics due to its appropriate conductivity and theoretically 100% spin polarization at Femi level. As (111) texture is a common structure in Fe3O4 films, the paper introduced the current studies on (111)-textured correlated spin transport and magnetic dynamics (magnetic anisotropy) in Fe3O4 films.
