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.

The amazing thing about this quantum material is that its only occur when some atoms swap places, introducing antisite disorder. The findings have been published in the journal Advanced Science.
