Superparamagnetic nanoparticle ensembles [PDF]
Superlattices and Microstructures, 2012 Magnetic single-domain nanoparticles constitute an important model system in magnetism. In particular ensembles of superparamagnetic nanoparticles can exhibit a rich variety of different behaviors depending on the inter-particle interactions.

Superparamagnetic Properties of Hemozoin [PDF]
Scientific Reports, 2016 AbstractWe report that hemozoin nanocrystals demonstrate superparamagnetic properties, with direct measurements of the synthetic hemozoin magnetization. The results show that the magnetic permeability constant varies from μ = 4585 (at −20 °C) to 3843 (+20 °C), with the values corresponding to a superparamagnetic system.

Superparamagnetic colloids in viscous fluids [PDF]
Scientific Reports, 2017 AbstractThe influence of a magnetic field on the aggregation process of superparamagnetic colloids has been well known on short time for a few decades. However, the influence of important parameters, such as viscosity of the liquid, has received only little attention.

Superparamagnetic Nanoparticles for Atherosclerosis Imaging [PDF]
Nanomaterials, 2014 The production of magnetic nanoparticles of utmost quality for biomedical imaging requires several steps, from the synthesis of highly crystalline magnetic cores to the attachment of the different molecules on the surface. This last step probably plays the key role in the production of clinically useful nanomaterials.

Shaping the Assembly of Superparamagnetic Nanoparticles [PDF]
ACS Nano, 2019 Superparamagnetism exists only in nanocrystals, and to endow micro/macro-materials with superparamagnetism, superparamagnetic nanoparticles have to be assembled into complex materials. Most techniques currently used to produce such assemblies are inefficient in terms of time and material.

Nanochains Formation of Superparamagnetic Nanoparticles [PDF]
The Journal of Physical Chemistry C, 2011 We present simulations on the aggregation of nanometer sized polydispersed superparamagnetic particles under the application of an external magnetic field. We make use of a Monte Carlo method, using a cluster-moving approach, as previously used in literature for ferrofluids. van der Waals attraction and magnetic anisotropy are taken into account in the
