As we can observe in Figure 5b, the average field of the SFD curve changes to higher values with respect to the Co content, reflecting the anisotropy

• nanostructures considered result from the interplay of complex phenomena arising from the complex nanoparticle-ensemble morphology of the structures as no individual nanoparticles are present. The pronounced expression and definition of a plasmon resonance band is thus hindered. In such a case, the optical

Here, the gold nanoparticle ensemble enables an extension of the dense field lines towards the furthermost gold nanoparticle, and thus, towards the electrode gap, facilitating a preferred deposition of the next hybrid structure at this specific site, and thus, chain growth. Figure 5b shows that

• the point for nanosolidus. Thus nanosolidus and nanoliquidus may be not interrelated. We call this difference between the end point of forth transition and starting point of back transition as ‘thermodynamic hysteresis’. Similar effect has been shown for a structural transition of Fe-nanoparticle

• ensemble subjected to temperature change [41]. The reason of such hysteresis is nonsymmetry of transforming path of a nanosystem with respect to the initial conditions leading to differences in two-phase loops of nanomelting and nanosolidification in presented case. For example, for Cu–Ni nanoparticle
