This thesis aims to contextualize original results, concerning especially the structure and magnetic properties, obtained during fundamental research on nanoparticles of selected iron-containing systems and employ these findings in testing the nanoparticles in chosen applications. The selected systems involved comprise iron-containing oxides (ferrites, and various polymorphs of iron(III) oxide, including ε-Fe2O3 and doped counterparts), and sulfides (greigite, chalcopyrite), all of which exhibit specific properties such as magnetic or structural transitions. Among the studied applications, the largest attention is devoted to the use of magnetic nanoparticles as contrast agents in MRI, and the analysis of their efficacy in contrast enhancement – their relaxivity – with respect to various factors. Further, magnetic solid-phase extraction is included as a representative analytical application and the thermoelectric applications of nanostructured phases are briefly introduced.
