G. Henriques et al.2024·10.1038/s44160-025-00743-5·arXiv:2407.20511AbstractUnderstanding and engineering the coupling of spins in nanomaterials is of central importance for designing novel devices. Graphene nanostructures with π-magnetism offer a chemically tunable platform to explore quantum magnetic interactions. Here, the authors demonstrate the successful on-surface synthesis of spin-1/2 antiferromagnetic Heisenberg chains with parity-dependent magnetization based on antiaromatic diaza-hexa-peri-hexabenzocoronene (diaza-HBC) units, and combine STM, nc-AFM, DFT calculations, and quantum spin models to establish the structures and magnetic properties of the chains on Au(111).Read more
