Controlled magnetic granular materials with different concentrations of magnetite
nanoparticles immersed in a non-conducting polymer matrix were synthesized and, their …

Magnetic properties of Co-Si O 2 granular films are displayed and explained by means of a
phenomenological model that takes into account the effects of magnetic interparticle …

We investigated the performance of Hall sensors with different Co–C ratios, deposited
directly in nanostructured form, using Co 2 (CO) 8 gas molecules, by focused-electron or ion …

The magnetic properties of nanoparticles have long been an object of study, but there
remains an irritating diversity of phenomena that await full comprehension. The main …

Granular metals offer tailorable electronic properties and play crucial roles in device and
sensor applications. We have fabricated a series of nonmagnetic granular CoSi 2 thin films …

We report on the application of generalized spectroscopic ellipsometry to the study of
oriented prolate ellipsoidal cobalt nanoparticles embedded in a silica thin layer. The …

We have measured the resistivities and Hall coefficients, RH, of a series of nonmagnetic Mo
x (SnO 2) 1− x nanogranular films with the Mo volume fraction x ranging from∼ 0.29 to 1. We …

Magnetic interactions in systems composed of nanoparticles in a matrix give rise to
phenomena that are observable through magnetic and magnetotransport measurements. In …

Co− TiO 2 nanocomposite films were prepared via magnetron sputtering at various substrate
temperatures. The films comprise Co particles dispersed in an amorphous TiO 2 matrix and …

Ferromagnetic metal‐insulator granular films suffer from superparamagnetism, which
causes a decrease in the values and temperature stabilities of the anomalous Hall effect …
