Skyrmions are topologically stable magnetic structures with unique properties, characterized by a swirling spin configuration [1]. These nanoscale quasiparticles have garnered significant attention in recent years for their potential applications in memory and logic devices and quantum computing. Although several methods have been proposed to create skyrmions, few challenges still remain such as energy consumption, scalability and creation speed for example. We propose a new method based on the plasmonic effect to create skyrmions and other topological textures. In order to clarify the mechanisms underlying ultrafast skyrmions, the effects of nanoparticle size, insulating layer thickness, and resonance wavelength were investigated. Through the optimization of these characteristics, the study shows that skyrmions may be created efficiently and that their properties can be tuned, providing opportunities for the development of customized magnetic structures for particular uses. A creation time in the range of picoseconds and low energy consumption make it possible to develop revolutionary logic devices and enhance data storage systems. By combining plasmonic and skyrmionic concepts, advanced spintronic devices can be developed.<\/span><\/p>\n<\/div>\n

Dr. Rachid Sbiaa is Full Professor at Sultan Qaboos University, Oman. He earned in 1996 his Ph.D. in Materials Science from Paris 7 University, France, following his Master’s in 1991 from the same University. Prior to his actual position, he has held various research positions at multiple company industries. He has also been a visiting professor and researcher at institutions such as Nanyang Technological University, University of Lille, and the National University of Singapore.<\/span><\/p>\n

His research is focused on the design and fundamental understanding of magnetic thin films and nanostructures, with particular emphasis on spin-transfer torque phenomena and their applications in low-power memory devices, neuromorphic computing, magnetic field sensors and high-frequency devices for communication. More recently, he has been exploring magnetic domain wall dynamics and the motion of skyrmions in nanowires for next-generation computing technologies.<\/span><\/p>\n
