Prof Yongbing Xu of the Department of Electronic Engineering has published his recent collaborative work in the journal of Science Advances.

His article, entitled ‘Experimental observation of dual magnetic states in topological insulators’, discusses the group’s recent studies into the magnetic properties of topological insulators, unique materials which are conductive at their surface, yet insulating on the interior.

They found, for the first time, that there exists a temperature window where the interior is nonmagnetic, but the surface is magnetic, which is key to allowing electrons to flow without losing energy. This work has exciting potential for next-generation electronics with minimal heating, leading to faster and more energy-efficient components.
