Magnetic spins in YTiO3 are synchronized by THz light, leading to a stronger and higher temperature ferromagnetic phase. Credit: © Jörg Harms, MPSD Researchers have used terahertz light pulses to induce ferromagnetism in a crystal at temperatures far above its normal transition temperature, paving the way for optically controlled memory […]
