研究了具有自旋簇状玻璃结构的尖晶石铁氧体Al0.2Ru0.8Fe2O4薄膜的室温光致磁化（PIM）。此外，薄膜具有明显的自旋电子材料性能，在0.6μB/unit cell下具有较低的饱和磁化强度和良好的导电性，自旋极化电子能级超过75%。高温PIM和与自旋电子学相关的电子特性的结合将产生一个研究和开发领域，利用自旋电子学领域中光学系统提供的自由度。
Room-temperature-photoinduced magnetization (PIM) was observed in spinel ferrite Al0.2Ru0.8Fe2O4 thin films with a spin-cluster-glass structure. Additionally, the films exhibited significant properties as spintronic materials, showing a low saturation magnetization under 0.6μB/unit cell and good conductivity with a high spin polarized electron level of over 75%. A combination of high-temperature PIM and the electronic properties associated with spintronics would generate an area of research and development that utilize the degrees of freedom offered by optical systems in the field of spintronics.
