A critical review of models for the dynamics of interacting magnetic nanoparticles is given. It
is shown that the basic assumptions in the Dormann–Bessais–Fiorani model are unrealistic …

The models proposed to account for the variation of the blocking temperature of a magnetic
particle in an assembly of interacting particles are re-discussed. Experimental results on the …

A model of the magnetic properties of a dispersion of interacting superparamagnetic
particles in a solid matrix is presented. The model uses Monte Carlo techniques and is …

We study the magnetic properties of spherical Co clusters with diameters between 0.8 nm
and 5.2 nm (25–7000 atoms) prepared by sequential sputtering of Co and Al 2 O 3. The …

The effects of a dipole-dipole interaction on the magnetic relaxation in a magnetic
nanoparticle system have been investigated using ac-susceptibility, magnetic relaxation …

The magnetic properties of Fe2O3 nanoparticles (average diameter∅≅ 3nm) in alumina
(68% Fe2O3 in weight) have been investigated by magnetization measurements. The …

ZnFe2O4 nanoparticles have been successfully prepared through a polyethylene glycol
(PEG)-assisted route. XRD, FTIR, TEM and VSM were used for the structural, morphological …

We study the magnetic properties of dispersions of uniformly sized, chemically synthesized
cobalt nanoparticles (NP's), observing a crossover from a blocked state to a …

The influence of the dipole-dipole interaction on the dynamics of monodispersive ensembles
of magnetic nanoparticles have been studied by Monte Carlo simulations. An increased …

Nano-crystalline chromium doped cobalt ferrite powders have been synthesized by PEG
assisted hydrothermal route. The structural, morphological and magnetic properties of the …
