Ga2-xFexO3的晶体结构和磁学性质
rystal structure and magnetic properties of Ga2-xFexO3
本文用经典的固相法制备了从0.7到1.3的GaFeO3（GFO）粉末样品，系统地研究了其结构、光学和磁性。EDX的结果表明，可以通过调整粉末中氧化铁含量来获得Fe元素的含量。XRD光谱和FULLPROF profile拟合表明，GFO粉末样品属于空间基团Pc21n的正交结构。除此之外，还得到相分离出现在x = 1.3的铁含量上。同时，磁性性能测量表明，GaFeO3是铁磁体，可以通过增加Fe含量来增强磁性，这对铁磁半导体的应用至关重要。
GaFeO3 bulks with x from 0.7 to 1.3 have been fabricated by using classic solid-state route. The structural, optical, and magnetic properties have been investigated systematically. The results of EDX demonstrated that the Fe content can be obtained by adjusting the Fe content in the powders. XRD spectra and FULLPROF profile fitting indicated that GFO bulks belong to the orthorhombic structure with space group Pc21n. Phase separation appeared at the Fe content of x=1.3. Meanwhile, the magnetic property measurements suggested that GaFeO3 is ferromagnetic, and magnetic properties can be enhanced by increasing the Fe content, which is of vital importance for the application of ferromagnetic semiconductors.
