The “melting point” of alkanethiol‐coated amorphous Fe 2 O 3 nanoparticles is investigated. The dependence of the melting temperature on the alkyl chain length is presented and compared with the results obtained by Luedkte and Landman, who carried out a comprehensive theoretical study on the structure and dynamics of nanocrystalline gold passivated by alkanethiol monolayers. It is shown that molecules coated on a chaotic amorphous structure have a “melting” phenomenon similar to that found on well‐organized nanocrystalline materials.
