Dr. Yonathan Anahory from HUJI’s Racah Institute of Physics and his research team study the world of the very small, observing materials on the nanoscale. A human hair, for example, is 100,000 nanometers wide. When the team was looking at images of the magnetism generated by nano-magnets, they discovered a completely new phenomenon: the magnetic material only retained magnetism on its edge – in fact only within 10 nanometers of the edge. Although very small, this "edge magnetism" could have wide applications in our daily lives. It could be used for designing the next-generation of nano-electronic devices with reduced power consumption and increased memory and processing capabilities.
