Nano-objects and thin films displaying molecular spin-crossover phenomena have recently attracted much attention. However, the investigation of spin crossover at reduced sizes is still a big challenge. Here we demonstrate that surface plasmon polariton waves propagating along the interface between a metal and a dielectric layer can be used to detect the spin-state changes in the latter with high sensitivity, even at the nanometer scale.
最近,展示分子自旋交叉现象的纳米物体和薄膜引起了广泛关注。然而,在减小尺寸下研究自旋交叉仍然是一个巨大的挑战。在这里,我们证明了沿着金属和介电层之间的界面传播的表面等离激元波可以用于高灵敏度地探测后者的自旋态变化,甚至在纳米尺度上也是如此。
