Ultra-Efficient Opto-Magnetic Control of Magnetization in Nanofilms
Reviewed by Lexie Corner on February 6, 2025 Researchers at Tohoku University have made a significant advance in magneto-optical technology. They have demonstrated magneto-optical torque that is approximately five times more efficient than conventional magnets. Study was published in Physical Review Letters . When circularly polarized light strikes the surface of a nano-thin layer of cobalt-platinum alloy, which…
