This study presents the preparation of magnetic carbon nanocomposites (MCNCs) through a two-step procedure: (i) in situ co-precipitation of magnetite (Fe3O4) nanoparticles into four different carbonaceous matrixes and (ii) post-pyrolysis treatment to

The stoichiometry and the effective anisotropy constant (K eff ) of several samples of iron-oxide nanoparticles with sizes between 12 and 51 nm, showing spheroidal and cubic shapes, were studied by means of Mössbauer spectroscopy at room temperature

Biomedical magnetic colloids commonly used in magnetic hyperthermia experiments often display a bidisperse structure, i.e., are composed of stable nanoclusters coexisting with well-dispersed nanoparticles. However, the influence of nanoclusters in th

Transparent pure and Fe-doped SnO 2 thin films were grown by pulsed laser deposition technique on LaAlO 3 substrates. X-ray diffraction shows that the films are polycrystalline and have the rutile structure. Surprisingly, the pure film presents magne

Aiming to analyze relevant aspects of interacting magnetic nanoparticle systems (frequently called interacting superparamagnets), a model is built from magnetic dipolar interaction and demagnetizing mean-field concepts. By making reasonable simplifyi

The present article reports studies on structural and magnetic properties of nanostructured Fe/MnO2 materials prepared by mechanosynthesis method, with Fe to MnO2 ratios of 20/80, 50/50 and 60/40. X-ray diffraction patterns indicate that the milled m

The magnetic properties of maghemite particles hosted in silica aerogel pores are studied in depth, with most of the focus on the magnetic relaxation mechanisms. It is shown that at room temperature, the system behaves as an ensemble of non-interacti

Iron silicide phases, grown on or into single‐crystals of silicon, can be produced by different techniques as reactive and molecular beam epitaxy, and ion implantation followed by recrystallisation processes. Different phases have been obtained dep

A study of the magnetic behavior of maghemite nanoparticles (NPs) in polyvinyl alcohol (PVA) polymer matrices prepared by physical cross-linking is reported. The magnetic nanocomposites (ferrogels) were obtained by the in situ co-precipitation of iro

Cubic-like shaped ZnxFe3−xO4 particles with crystallite mean sizes D between 15 and 117 nm were obtained by co-precipitation. Particle size effects and preferential occupation of spinel tetrahedral site by Zn2+ ions led to noticeable changes of phy
