Attend a seminar exploring nano- and microstructures for ultrafast spin control using optical and terahertz pulses, presented by Prof. Vladimir Belotelov from Moscow State University. Discover how modern microelectronics requires significant increases in clock frequencies up to terahertz ranges, necessitating the use of optical and terahertz electromagnetic waves for device control. Learn about the current limitations in control efficiency for practical applications and explore a comprehensive research cycle aimed at solving this problem through the development and application of nano- and microstructures with optical and terahertz resonances, including plasmonic and dielectric antennas and metasurfaces. Understand how these structures enable localization and redistribution of electromagnetic radiation in magnetic structure regions, efficiently excite high-frequency spin dynamics, and achieve ultrafast magnetization reversal. Examine the critical importance of these developments for information recording and reading devices, terahertz emitters and detectors, as well as magnonic and spintronic memory elements.
