Superparamagnetic nanoparticles, magnetic properties and application

Kroz ovaj završni rad predstavljene su superparamagnetske nanočestice, njihovo ponašanje te primjene u medicini i tehnologiji. Objašnjena su najbitnija magnetska ponašanja i fenomeni, poput Neelova vremena relaksacije, temperature blokiranja, ZFC i FC krivulja te krivulja magnetske histereze. Također su navedene i objašnjene različite vrste magnetizma u materijalima. U završnom dijelu prikazane su najznačajnije primjene superparamagnetskih nanočestica u poljima IT industrije, medicine i tehnologije.Through this thesis superparamagnetic nanoparticles have been presented. The most important magnetic properties and phenomena of magnetic nanoparticles are explained, such as Neel's relaxation time, blocking temperature, ZFC and FC curves, hysteresis curves. In the first part of thesis, magnetic behavior are generally explained with classification of all types of magnetism in the materials. Further, the focus of this research is on magnetic properties and applications of nano-sized object (nanoparticles). Finally, in the last part of the work are presented applications of magnetic nano-materials in different parts of technology and medicine
