Influence of Protected Annealing on the Magnetic Properties of γ-Fe2O3 Nanoparticles
TL;DR: In this article, the influence of post-synthesis thermal treatments on 7-nm-sized γ-Fe2O3 nanoparticles prepared by room temperature coprecipitation of ferric and ferrous salts in alkaline medium, followed by the dispersion of the preformed particles in a sol-gel silica binder.

Ionic ferrofluid: Optical properties
TL;DR: In this article, the alignment of magnetic colloidal particles along a magnetic field induces a briefringence of the solution, which can be used to determine the size distribution of the grains.

On the origin of the surface magnetic anisotropy in manganese-ferrite nanoparticles
TL;DR: In this paper, the surface anisotropy of manganese-ferrite nanoparticles is explained using a model that includes the single-ion (magnetocrystalline) term plus the magnetoelastic term.
