title: Preferential Excitation of the Hybrid Magnetic-Electric Mode as a Limiting Mechanism for Achievable Fundamental Magnetic Resonance in Planar Aluminum Nanostructures.
abstract: Aluminum is a promising candidate for light at the nanoscale in the ultraviolet (UV); however, the realization of magnetic resonance in the UV range remains challenging due to stringent dimensional requirements arising from the intrinsic loss caused by the interband transition. Here, the mode interaction with the aluminum interband transition and preferential excitation of the hybrid magnetic-electric mode, as discovered in ultrasmall Al resonators, are reported.
