Shulyma S. Cluster-formation into kerosine-magnetite magnetic liquid system

The thesis is dedicated to the cluster formation processes investigation in kerosene-magnetite based magnetic liquid systems. The special attention is drawn to the cluster structure formation and transformation investigation in the classical and structured kerosene-magnetite ferrofluids under the influence of pulse magnetic field and temperature. It has been shown that nanoparticles coating rate decreasing leads to formation of cluster of limiting dimension. It is established that an external magnetic field leads to decreasing of such cluster's destruction temperature. The optical extinction trend inversion effect spectral dependencies and simulation results allowed to establish the lateral character of cluster growth under the pulse magnetic field influence in classical ferrofluids. The method for determining magnetic nanoparticles clusters growth rate in classical ferrofluids by the magnetic field influence was proposed. The technique for the brand new type of material (controlled composite material) creating was proposed.
