New Discovery Could Lead to Increased Magnetism at Higher Temperatures
A new study has found that topology-driven magnetism can be achieved at much higher temperatures than was previously thought possible. Scientists at the University of California, Riverside and the University of Houston have made a discovery that could help push the limits of magnetic materials to higher temperatures and make them more resistant to external magnetic fields. The research, published in the journal Nature Communications, could lead to advances in a wide range of applications such as data storage, spintronics, and quantum computing.
The research team used a technique called “topological band theory” to show that topological insulators, materials that can conduct electricity along their surfaces but not through their bulk, can also exhibit magnetism at much higher temperatures than previously thought. This is a breakthrough in the field of topology-driven magnetism, which could lead to the development of new materials that are more resistant to external magnetic fields, making them suitable for use in a variety of applications.
