International audience; Fluids responding to magnetic fields (ferrofluids) offer a scene with no equivalent in nature to explore long-range magnetic dipole interactions. Here, we studied the very original class of binary ferrofluids, embedding soft a

The synthesis and characterization of original ferrite multishell magnetic nanoparticles made of a soft core (manganese ferrite) covered with two successive shells, a hard one (cobalt ferrite) and then a soft one (nickel ferrite), are described. The

Synthesis And Properties Of Magnetic Nanoparticles With Tunable Magnetic Anisotropy Energy

Autor: Vincent Dupuis, Sophie Neveu, Véronica Gavrilov-Isaac, Sébastien Abramson, Merwen Aouadi

Publikováno v: MRS Proceedings. 1708

In this paper, we discuss several strategies to tailor magnetic properties related to the magnetic anisotropy energy, such as the blocking temperature or the low temperature coercivity, of magnetic nanoparticles or materials made with magnetic nanopa
