The extracted Gilbert damping values show no significant dependence on stacking order or on the choice of normal-state superconductor. A thickness-dependent analysis of the NbRe/Py bilayer reveals a clear increase in α with the non-magnetic layer thickness, consistent with spin-pumping-induced dissipation. These results provide a concise experimental picture of damping and spin transport in FM/NM systems involving superconducting materials in their normal state7 p.application/pdfengcc-by-nc-nd (c) Vicente, 2026http://creativecommons.org/licenses/by-nc-nd/4.0/FerromagnetismeSpin (Física nuclear)Treballs de fi de grauFerromagnetismNuclear spinBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
