Surprise in the quantum world: Disorder leads to ferromagnetic topological insulator

Magnetic topological insulators are an exotic class of materials that conduct electrons without any resistance at all and so are regarded as a promising breakthrough in materials science. Researchers from the Cluster of Excellence ct.qmat in Würzburg and Dresden have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing the ferromagnetic topological insulator MnBi6Te10 from the manganese bismuth telluride family.
