论文摘要
我们已经研究了退火处理对先前使用射频（RF）Magnetron溅射的SRFE_12_O_19晶体生长的影响。为了实现这一目标，已经分析并进行了比较，并进行了分析并进行比较，以确定其结构，组成和磁性特性的差异。通过不同的分析技术获得的结果，尤其是Mössbauer光谱以及EXAFS和XANES数据，这表明该膜成长的膜由纳米晶型磁石纳米颗粒和氧化锶无定形。在退火膜中发现了样品平面中具有c轴向取向的腹膜六体典型结构。
We have studied the influence of annealing treatment on the crystalline growth of SrFe_12_O_19 previously deposited on Si (100) substrates using radio frequency (RF) magnetron sputtering. For this goal, two grown films, with and without \textit{ex-situ} heating step, have been analysed and compared to determine the differences in their structural, compositional and magnetic properties. The results obtained by the different analysis techniques, in particular Mössbauer spectroscopy together with EXAFS and XANES data, suggest that the as-grown film is composed of nanocrystalline maghemite nanoparticles and amorphous strontium oxide. A strontium hexaferrite canonical structure with c-axis orientation in the sample plane was found for the annealed film.
