Researchers have discovered that trapping light in specific magnetic materials can greatly amplify their properties, offering potential innovations like magnetic lasers and a fresh perspective on optically controlled magnetic memory. A groundbreaking study conducted by Vinod M. Menon and his team
Scientists have discovered that trapping light within certain magnetic materials can significantly enhance their intrinsic properties. Their study examined a specific layered magnet capable of hosting powerful excitons, enabling it to trap light independently. The optical reactions of this material to magnetic occurrences are remarkably stronger than those in regular magnets.
A groundbreaking study conducted by Vinod M. Menon and his team at The City College of New York reveals that trapping light within magnetic materials can significantly boost their intrinsic properties. These heightened optical reactions in magnets pave the way for innovations in magnetic lasers, magneto-optical memory devices, and even in emerging quantum transduction applications.
“Since the light bounces back and forth inside the magnet, interactions are genuinely enhanced,” said Dr. Florian Dirnberger, the lead author of the study. “To give an example, when we apply an external magnetic field the near-infrared reflection of light is altered so much, the material basically changes its color. That’s a pretty strong magneto-optic response.”
On how the advances can benefit ordinary people, study co-author Jiamin Quan pointed out that: “Technological applications of magnetic materials today are mostly related to magneto-electric phenomena. Given such strong interactions between magnetism and light, we can now hope to one day create magnetic lasers and may reconsider old concepts of optically controlled magnetic memory.”
