| الوصف: | International audience ; This theoretical study unveils the potential for ultrafast skyrmion generation in magnetic thin films, driven by the remarkable plasmonic properties of gold nanoparticles. By combining the plasmonic, photothermal, and micromagnetic analysis, we explore size-dependent light absorption, resonance wavelength, and electric field distribution around the nanoparticles. Our findings highlight the crucial role of the insulating layer's thickness in enhancing plasmonic effects, offering tunable absorption characteristics. Micromagnetic calculations demonstrate the efficient creation of Néel skyrmions in the range of a few tens of ps, showcasing a breakthrough in magnetic phenomena and opening thus a path for functional skyrmionic-based devices. |
