Films of 60 nm thickness were prepared by magnetron co-sputtering at different substrate temperatures (TS), and those deposited at room temperature were later annealed at various temperatures (Ta). X-ray diffraction confirmed (001) [110] Co2FeGe || (001) [100] MgO epitaxial growth. A slight tetragonal distortion of the film cubic structure was found in all samples due to the tensile stress induced by the mismatch of the lattice parameters between Co2FeGe and the substrate. Improved quality of epitaxy and the formation of an atomically ordered L21 structure were observed for films processed at elevated temperatures. The values of magnetization increased with increasing TS and Ta. Ferromagnetic resonance (FMR) studies revealed 45° in-plane rotation of the easy anisotropy axis direction depending on the degree of the tetragonal distortion. The film annealed at Ta = 573 K possesses the minimal FMR linewidth and magnetic damping, while both these parameters increase for another TS and Ta. Overall, this study underscores the crucial role of thermal treatment in optimizing the magnetic properties of Co2FeGe films for potential spintronic and magnonic applications. info:eu-repo/grantAgreement/ES/DGA-FEDER E28-23R info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2020-112914RB-100/AEI/10.13039/501100011033 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 4.3 2024 MATERIALS SCIENCE, MULTIDISCIPLINARY 177 / 461 = 0.384 2024 Q2 T2 NANOSCIENCE & NANOTECHNOLOGY 69 / 147 = 0.469 2024 Q2 T2 CHEMISTRY, MULTIDISCIPLINARY 81 / 239 = 0.339 2024 Q2 T2 PHYSICS, APPLIED 57 / 187 = 0.305 2024 Q2 T1 0.811 2024 Chemical Engineering (miscellaneous) 2024 Q1 Materials Science (miscellaneous) 2024 Q2 9.2 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Popadiuk, Dariia Postolnyi, Bogdan Bunyaev, Sergey Štrichovanec, Pavel Pardo, José Ángel Universidad de Zaragoza (orcid)0000-0002-0111-8284 Algarabel, Pedro Antonio (orcid)0000-0002-4698-3378 Salyuk, Olga Korenivski, Vladislav Kakazei, Gleb N.
