A set of∼ 9 nm CoFe2O4 nanoparticles substituted with Zn2+ and Ni2+ was prepared by
thermal decomposition of metallic acetylacetonate precursors to correlate the effects of …

Dense systems of magnetic nanoparticles may exhibit dipolar collective behavior. However,
two fundamental questions remain unsolved: i) whether the transition temperature may be …

Magnetic nanoparticles represent complex but very interesting objects. They combine the
bulk properties with novel phenomena emerging at the nanoscale due to finite-size effects …

The potential of magnetic nanoparticles for acting as efficient catalysts, imaging tracers or
heating mediators relays on their superparamagnetic behaviour under alternating magnetic …

Abstract ZnFe 2 O 4 (ZFO) has emerged as anode material for lithium ion batteries (LIBs)
thanks to its intercalation mechanism combining conversion and alloying reactions. The …

We investigated the flexibility of high-temperature thermal decomposition synthesis to
design magnetic nanoparticles (NPs) with engineered properties. We prepared spinel iron …

Starch-coated magnetic iron oxide nanoparticles have been synthesized by a simple, fast,
and cost-effective co-precipitation method with cornstarch as a stabilizing agent. The …

We perform computer simulations to study the relaxation in a one-dimensional chain of
dipolar interacting magnetic nanoparticles (MNPs). Using the two-level approximation of the …

We study the relaxation of long chains of magnetic nanoparticles (MNPs). In spite of the
simplicity of this system, there is no theoretical framework for this basic assembly. Using the …

When preparing nanostructured magnetic materials, the presence of an amorphous
component is often considered a weakness of the synthesis method and a waste of material …
