Abstract. The purpose of this work is to develop a bottom-up nanostructure assembling technology for carbon-based spintronic and caloritronic devices. To enhance magnetic interactions along the walls of nanotubes, a controlled synthetic chemical technology is used, which is based on a two-stage method, which at the first stage involves the functionalization of carbon nanotubes, and then the addition of the organometallic complex to carbonyl groups. Then the system is characterized as a whole, including magnetometric analysis, as well as transport measurements at low temperatures. The mesoscopic electron-spin correlations are observed, as well as a clear transition from superparamagnetism to weakly ferromagnetic, depending on the functionalization method. Then, a new nanoscale assembly technology was demonstrated, based on the use of nano tweezers made from an alloy with shape memory effect. Device configurations include quantum interferometers, rings, cross contacts, as well as thin network structures that can be manipulated using nano tweezers. Since carbon nanotubes were functionalized by nanoscale magnetic fragments, such devices are interesting for new applications in spintronics and caloritronics.

Key words: nanowires, three-dimensional nanomanipulation, CNT, bottom-up nano-assembling, ring structures, pig-tail structures, shape memory effect, Ti2NiCu alloy.
