CostacheThe focus of this Treball Fi de Grau (TFG) is the study of magnon’s dispersion relation in a thin film of YIG at room temperature when applying an in-plane magnetic field. The magnon dispersion relation was first analyzed in order to better understand the conditions for the BEC: material thickness and applied magnetic field direction and intensity. Secondly, the ferromagnetic resonance was experimentally studied in a thin YIG film with the theoretically analyzed geometry, more specifically the uniform mode (k = 0) and spin-wave resonance.5 p.application/pdfengcc-by-nc-nd (c) Villena, 2024http://creativecommons.org/licenses/by-nc-nd/3.0/es/Spin (Física nuclear)Pel·lícules finesTreballs de fi de grauNuclear spinThin filmsBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
