Abstract: Technique for determination the energy of uniaxial and cubic magnetic anisotropy in magnetic nanoparticles from experimental magnetization curve is proposed. The technique is based on the numerical simulation of experimental magnetization curve in the terms of the composite mode of the Stoner–Wolfarth model. Investigation of magnetic anisotropy for Co-Ni nanoparticles is carried out by proposed technique.

Keywords: numerical modeling, ferromagnetic nanoparticles, magnetic anisotropy, Stoner–Wolfart model.
