Magnetic properties of the nanostructures are particularly associated with their crystalline and interface quality. In turn these features strongly depend on a fabrication technique (e.g. MBE vs. sputtering – energy of depositing atoms) and technological parameters (e.g. growth temperature – crystalline structure, sharpness of the interfaces). They affect various components of magnetic anisotropy: magnetocrystalline (mono- or polycrystalline structure, orientation, textured columnar growth), magnetoelastic (non-relaxed strains) or interface (roughness or alloying) This is a long story and the various chapters depend on a nanostructure character and type of building materials.

There are different types of magnetic nanostructures like, self assembled, induced by different force fields . Even in these too there are various types like self assembled ring structures, chains, loops, columns etc. Each one forms under different preparation conditions. Magnetic properties of these structures are also different and have also different applications. As stated above there are various books and papers are available.
