Optical, magnetic, and magneto-optical properties have been investigated for the a-Fe2O3-doped transparent glasses irradiated with an infrared femtosecond laser and subsequently annealed. The values of the saturation magnetization at room temperature for the irradiated glasses were increased compared with the as-prepared samples, which is due to the precipitation of the ferrimagnetic ferrite nanoparticles (NPs). By adding further dopants as precursors of plasmonic metals, Au or Al NPs were space-selectively precipitated together with the ferrite NPs in a confined region after irradiation and thermal annealing. In the case of the glass codoped with Al, magneto-optical Faraday effect was enhanced and exhibited a negative distinct peak ascribed to a coupling between the ferrimagnetism of ferrite NPs and the localized surface plasmon resonance of Al NPs.

研究了用红外飞秒激光辐照并随后退火的 a-Fe2O3 掺杂透明玻璃的光学、磁性和磁光特性。与制备的样品相比，辐照玻璃的室温饱和磁化强度值有所增加，这是由于亚铁磁性铁氧体纳米粒子（NP）的沉淀所致。通过添加更多掺杂剂作为等离子体金属的前体，在辐照和热退火后，Au 或 Al NP 与铁氧体 NP 一起在有限区域中进行空间选择性沉淀。在玻璃共掺杂Al的情况下，磁光法拉第效应增强并表现出负的明显峰，归因于铁氧体纳米粒子的亚铁磁性和Al纳米粒子的局域表面等离子体共振之间的耦合。
