This microreview highlights recent techniques used to determine the spin state at or around room temperature in nanoscale objects composed of iron(II) spin‐crossover complexes. Complexes have been studied in the form of thin films, nanoparticles, single molecules or oligomolecular aggregates. Three approaches are presented: Surface plasmon polariton resonance in films on Ti/Au substrates, the determination of single‐particle current–voltage characteristics between gold electrodes, and current‐imaging tunnelling spectroscopy performed on highly oriented pyrolytic graphite‐adsorbed strings of oligonuclear, bead‐like complex aggregates.
