Journal ArticleDOI
Coercivity of Fe‐SiO2 nanocomposite materials prepared by ball milling
TL;DR: In this article, the authors studied the variation with the milling time of both the saturation magnetization and the coercive force of these samples and found that the rapid increase of coercivity with the decrease of temperature observed in the low temperature range suggested the presence of superparamagnetic particles in the samples.
Journal ArticleDOI
The effect of the distribution of vacancies on the magnetic properties of γ – Fe2O3 particles
TL;DR: In this paper, the magnetic properties of uniform α-Fe2O3 particles obtained by homogeneous hydrolysis in solution and directly by spray pyrolysis methods were analyzed by using x-ray and electron diffraction.
Journal ArticleDOI
Detailed analysis of the crystallization of the Co-P amorphous system: Kinetics, influence of magnetic order, and formation of textures
TL;DR: The crystallization kinetics of the amorphous Co-P system and the influence of the magnetic order of the samples on the microstructural and magnetic features of the crystallization product have been studied in this article.
Journal ArticleDOI

TL;DR: In this article, a comparative study of the magnetic behavior of FCC alloy CoNi nanoparticles, embedded in a silica matrix and prepared by the ion implantation and sol-gel techniques, is presented.
Journal ArticleDOI
Magnetic properties of Ni nanoparticles dispersed in silica prepared by high-energy ball milling
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.
