Abstract: We show that the magnetic properties of antiferromagnetic layered NiCl$ {2}$can be altered under nano-sizing depending on dimensionality and morphologytype of the corresponding nano-forms. By means of Monte-Carlo simulationswithin classical Heisenberg model, the spin ordering, magnetic part of heatcapacity C$ {v}$ and N\-eel temperatures T$ {N}$ for multi-walled NiCl$ {2}$nanotubes and a fullerene were calculated and analyzed in comparison with thebulk NiCl$ {2}$ and multilayered two-dimensional NiCl$ {2}$ crystals andnanostripes. We have found that the nano-structuring of NiCl$ {2}$ at the sizereducing and at the formation of the closed structures can influencepropitiously on the preservation of antiferromagnetic properties.
