Engineering Ferrimagnetic Interactions in Molecular Quantum Systems
Researchers synthesized heterospincoupled molecular systems by covalently linking spin-1/2 (spin-1/2) and spin-1 (spin-1) nanographenes. This created dimers and trimers that exhibit distinct ferrimagnetic ground states, including compensated (S=0) and uncompensated (S=3/2). The work establishes a platform for designing tunable, multi-level quantum systems.
