Résumé
The Cover Feature shows modeling of a 1D Ising‐like Hamiltonian chain for binuclear spin‐crossover materials accounting for two‐, three‐ and four‐body intra‐ and inter‐binuclear interactions. Exact treatment is carried out within the frame of the transfer matrix method. In the case of competing anti‐ferroelastic intra‐dinuclear and ferroelastic inter‐dinuclear interactions, thermally induced two‐, three‐ and four‐step transitions are obtained. When interchain interactions are considered, multistep hysteretic transitions are generated, reproducing the experimental observations. More information can be found in the Research Article by K. Boukheddaden and co‐workers (DOI: 10.1002/cphc.202400238).
