Understanding Spin Crossover Phenomena: From Fundamentals to Industry Relevance

Spin crossover refers to the ability of certain transition metal complexes—most notably those of iron(II)—to reversibly switch between high-spin and low-spin states in response to external stimuli such as temperature, pressure, or light. This phenomenon hinges on the subtle interplay of ligand field strength, electron pairing energies, and lattice interactions.
