TL;DR: In this article, structural and magnetic properties of isometric nanoparticles ranging from 3 to 14 nm with a narrow particle size distribution have been studied, and it has been shown that there is a strong dependence on the average crystallite size.

TL;DR: In this paper, the structural and magnetic properties of spherical nanoparticles with a narrow particle size distribution have been studied and partial cationic order is observed for particles larger than 10nm in diameter while the smallest ones are disordered.

TL;DR: In this paper, the authors report on the hysteretic and relaxational behavior of Fe-Ba hexaferrite nanocomposite samples prepared by ball milling, including data on the temperature dependence of the coercive force, on the relationship between the field evolution of the isothermal and the demagnetization remanences and on the time evolution of magnetization at those remanence.

TL;DR: In this paper, the magnetic properties of mechanically ground nanosized Ni particles dispersed in a SiO2 matrix were analyzed and the authors concluded that the magneto-elastic anisotropy plays the dominant role in determining the magnet properties of the particles.

TL;DR: In this article, the phase distribution and magnetic properties of nanoparticulate Fe/SiO2 samples prepared by high-energy ball milling were analyzed and it was suggested that the elevated coercivities measured in the samples are linked to the coupling of the core of the particles (α-Fe) with a highly disordered phase present in their surface region and whose behavior exhibits some similarities with a spin-glass phase.
