Micromagnetic simulations with different values of the relevant parameters have been performed to reproduce the experimental results. The role of the exchange interaction between cores is studied. An analysis of the resulting magnetisation hysteresis loops is done, as well as the vorticity and topological properties of the magnetisation configuration.5 p.application/pdfengcc-by-nc-nd (c) García, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/NanopartículesPropietats magnètiquesTreballs de fi de grauNanoparticlesMagnetic propertiesBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
