The study of spin crossover compounds by means of theoretical or experimental approaches has provided interesting results in recent decades. The main feature of such compounds is the change in the spin state induced by many different external stimuli, i.e. temperature, light, pressure, solvent coordination and the electric field. Spin crossover systems are potentially more useful than other magnetic molecules because their switching behaviour can occur closer to room temperature, and they are thus candidates for use in spintronic devices. Here, I review the state of the art in quantum chemical approaches to the study of such systems and discuss experiments that have focused on transport properties in single-molecule, nano-objects or thin-film spin crossover systems.
近年来，通过理论或实验方法研究自旋交叉化合物取得了有趣的成果。这类化合物的主要特征是其自旋状态在外加许多不同刺激因素（如温度、光、压力、溶剂配位和电场）的作用下发生变化。自旋交叉体系比其他磁性分子更有用，因为其开关行为可以在更接近室温的条件下发生，因此它们是用于自旋电子器件的候选材料。在此，我综述了研究这类体系的量子化学方法的最新进展，并讨论了专注于单分子、纳米物体或薄膜自旋交叉体系输运性质的实验。
