Composition, structure, electronic properties and electric and magnetic behavior have been analyzed by different techniques including XRR, XRD, TEM microscopy, SQUID magnetometry, electrical resistivity and XAS spectroscopy. After annealing, an Ir1–xCoxO2 substitutional solid solution phase with rutile crystal structure was achieved for a wide Co-doping range 0 ≤ x ≤ 0.6. Starkly departing from the highly insulating behavior of CoO and Co3O4, the electrical resistivity at room temperature of our films is only slightly higher than that of IrO2. Likewise, our work shows that the magnetic response of the doped films is very similar to that of the paramagnetic parent IrO2. Neither ferromagnetism nor enhanced paramagnetism is observed. XAS spectra indicate a Co3+ oxidation state and, correspondingly, an oxidation state of ∼5+ for Ir ions in the polycrystalline Ir0.6Co0.4O2 film. By application of sum rules, a 13 % increase in the spin–orbit coupling is found despite the lattice shrinkage causes a detrimental bandwidth broadening. 000128012 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FSE/E12-23R-RASMIA$$9info:eu-repo/grantAgreement/ES/AEI/PID2020-115159GB-I00/AEI/10.13039/501100011033$$9info:eu-repo/grantAgreement/EC/H2020/101007825/EU/ULtra ThIn MAgneto Thermal sEnsor-Ing/ULTIMATE-I$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 101007825-ULTIMATE-I$$9info:eu-repo/grantAgreement/EC/H2020/730872/EU/Convenient Access to Light Sources Open to Innovation, Science and to the World/CALIPSOplus$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 730872-CALIPSOplus$$9info:eu-repo/grantAgreement/EC/H2020/872631 /EU/Memristive and multiferroic materials for emergent logic units in nanoelectronics/MELON$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 872631 -MELON 000128012 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000128012 590__ $$a5.8$$b2023 000128012 592__ $$a1.103$$b2023 000128012 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b109 / 439 = 0.248$$c2023$$dQ1$$eT1 000128012 593__ $$aMaterials Chemistry$$c2023$$dQ1 000128012 591__ $$aMETALLURGY & METALLURGICAL ENGINEERING$$b8 / 90 = 0.089$$c2023$$dQ1$$eT1 000128012 593__ $$aMetals and Alloys$$c2023$$dQ1 000128012 591__ $$aCHEMISTRY, PHYSICAL$$b51 / 178 = 0.287$$c2023$$dQ2$$eT1 000128012 593__ $$aMechanics of Materials$$c2023$$dQ1 000128012 593__ $$aMechanical Engineering$$c2023$$dQ1 000128012 594__ $$a11.1$$b2023 000128012 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000128012 700__ $$0(orcid)0000-0002-0901-8341$$aHerrero-Albillos, J.$$uUniversidad de Zaragoza 000128012 700__ $$0(orcid)0000-0002-1296-4793$$aAguirre, M.
