Objective
The main goal of the project is to elaborate the fundamentals of the newly developed technique for the preparation of magnetic nanocomposite materials with controlled size and shape of magnetic nanoparticles. The method involves the use of anion-substituted layered double hydroxides (LDH) as solid-state two-dimensional nanoreactors for synthesis of magnetic metallic and oxide nanostructures in diamagnetic or paramagnetic oxide matrices. It is believed that successful implementation of the project will result in the creation of a new family of Fe-, g-Fe2O3-, Ni- and Co-based magnetic nanomaterials with the predefined physicochemical properties suitable for magnetic storage device applications.
The project will specifically address the following scientific issues:
effect of the chemical composition of initial layered double hydroxides on the structure and properties of the resulting magnetic nanostructures.
optimization of conditions for the formation of nanocomposites with zero-, one- and two-dimensional metal nanoparticles.
investigation of the mechanism of the formation of nanostructures with specific morphology.
study of size- and dimension-related magnetic properties of nanocomposites.
preparation of materials in the form suitable for future applications.
In the present research Fe-, g-Fe2O3-, Co- and Ni-based magnetic nanoparticles will be prepared using LDH precursors. It is expected that the variation of the conditions during the synthesis will enable one to control size and dimensionality of the nanoparticles, as well as their magnetic properties. The investigation calls for a deep understanding of the mechanism of the nanophase formation and its dependence on the structure and composition of the precursors. Joint efforts of all research groups will be concentrated on the preparation and characterization of the above mentioned nanocomposites using shared experimental facilities.
The interdisciplinary nature of the project is reflected by the fact that it brings together five teams, whose major interests lie in three different fields, including materials chemistry (MSU, IChP), materials science (EMAT, INNOVENT), and solid state physics (IChP, IPHYS, INNOVENT). In addition, one of the partners (INNOVENT) represents industrial research, which ensures that the results of the project implementation (if successful) will be quickly brought to technological application.
