Ferrocene is an organometallic compound, consisting of a magnetic Fe atom placed in between two cyclopentadienil organic rings. When placed on top of a metallic surface, ferrocene molecules tend to self-organize, i.e., to form a perfectly uniform bidimensional lattice.
 Due to this property, in combination with its intrinsic magnetic properties, this compound is under intensive investigation for its potential applications to areas such as low-dimensional magnetism and spintronics. In this work, we have made an important progress in the understanding of the mechanisms controlling the self-assembly of ferrocene on clean Cu(111) and Cu(100) surfaces.
