摘要

使用射频磁控溅射法制备了生长在氧化镁（111）单晶衬底上的镍锌铁氧体薄膜，靶材的标称成分为 Ni0.5Zn0.5Fe2O4。随后进行了 X 射线衍射 (XRD)，发现了镍锌铁氧体结构的特征反射，证实了铁氧体的独特形成。X 射线光电子能谱（XPS）显示，在镍锌铁氧体的晶体结构中存在适当价态的金属离子。在薄膜中观察到的结合能变化归因于 Fe3+ 和 Zn2+ 或 Ni2+ 离子环境的变化，这是阳离子在四面体和八面体位点的非平衡分布造成的。饱和磁化和矫顽力场分别为和 513 ± 32 Oe。此外，还利用基于共面波导（CPW）光谱仪的宽带 FMR 光谱进行了铁磁共振研究。

Growth, magnetic, and electronic properties of Ni-Zn ferrites thin films

Thin films of Ni-Zn ferrite grown on MgO(111) single crystal substrate were prepared using radiofrequency magnetron sputtering, with a target of nominal composition Ni0.5Zn0.5Fe2O4. Subsequently, x-ray diffraction (XRD) was performed, which revealed characteristic reflections of a Ni-Zn ferrite structure, confirming the unique formation of the ferrite. X-ray photoelectron spectroscopy (XPS) revealed the presence of metal ions in their appropriate valence states within the crystalline structure of the Ni-Zn ferrite. The variation in binding energy observed in the thin film is attributed to changes in the environment of Fe3+ and Zn2+ or Ni2+ ions, resulting from the non-equilibrium distribution of cations in tetrahedral and octahedral sites. The saturation magnetization and the coercivity field were and 513 ± 32 Oe, respectively. In addition, ferromagnetic resonance studies were made using broad-band FMR spectroscopy based on a coplanar waveguide (CPW) spectrometer.
