寻找具有可调磁性和光学性质的多功能材料是实现未来集成光学器件的关键任务。垂直取向纳米复合材料（货车）薄膜为多功能材料设计提供了一个独特的平台。在这里，一个新的金属氧化物货车已被设计与等离子体Au纳米柱嵌入在铁磁La 0.67 Sr 0.33 MnO 3（LSMO）矩阵。这种Au-LSMO纳米复合材料在可见光范围内呈现出有趣的等离子体共振和磁各向异性性质，它们分别由Au和LSMO相功能化。此外，金属和电介质氧化物的垂直排列的纳米结构导致近场电磁波操纵的双曲线性质。这种光学和磁性响应可以通过调整Au和LSMO相的组成来进一步定制。
Searching for multifunctional materials with tunable magnetic and optical properties has been a critical task toward the implementation of future integrated optical devices. Vertically aligned nanocomposite (VAN) thin films provide a unique platform for multifunctional material designs. Here, a new metal–oxide VAN has been designed with plasmonic Au nanopillars embedded in a ferromagnetic La0.67Sr0.33MnO3(LSMO) matrix. Such Au–LSMO nanocomposite presents intriguing plasmon resonance in the visible range and magnetic anisotropy property, which are functionalized by the Au and LSMO phase, respectively. Furthermore, the vertically aligned nanostructure of metal and dielectric oxide results in the hyperbolic property for near-field electromagnetic wave manipulation. Such optical and magnetic response could be further tailored by tuning the composition of Au and LSMO phases.
