The work, led by scientists from New York College, explores the properties of a complex multilayer magnet with bound excitons, a class of quasiparticles known for their strong optical interactions. This special feature allows the material to catch the light.

As a result of careful experiments, the researchers determined that the optical response of this material to magnetic phenomena significantly exceeds the capabilities of ordinary magnets.

Florian Dirnberger, lead author of the published article, explained:

When light enters the magnet, its interaction becomes essentially stronger.

This observation is in stark contrast to the typical dim response of light to magnetic forces. In this case, the reflection of the near-infrared light spectrum in the material has undergone such dramatic changes that its shade itself has changed.

Why is this important?

The implications of this discovery have promising potential for practical applications. Scientists see a future where this new effect can contribute to the creation of magnetic laser devices, as well as provide a re-evaluation of existing magneto-optical media concepts.

This groundbreaking research aims to rethink the relationship between light and magnetism and pave the way for new technological developments.
