Natural van der Waals heterostructural single crystals with magnetic and topological properties
(PHYSorg.com Physics)

Heterostructures with magnetism and topology (geometry) are promising materials to realize exotic topological quantum states. However, such materials are challenging to engineer or synthesize. In a new report on Science Advances, Jiazhen Wu and an interdisciplinary research team in the departments of Materials Research, Optoelectronic Science, Physics, Condensed Matter Research and Advanced Materials in Japan and China, reported the development of natural magnetic van der Waals heterostructures. The constructs exhibited controllable magnetic properties while maintaining their topological surface states.
