Anisotropy in FeCo nanoparticles, a first step
Résumé
In this article, we study the intrinsic magnetic properties of diluted FeCo clusters nanoparticles embedded in an inert amorphous carbon matrix. We report an enhancement of the magnetic anisotropy energy (MAE) after annealing demonstrated by superconducting quantum interference device (SQUID) measurements and adjustments. Rutherford backscattering spectrometry (RBS) was used to quantify the sample stoichiometry and concentration.
