All the experiments have been carried out on thin films of IrO2, the thickness and crystallinity of the each film being specified in each file. X-ray reflectivity (XRR) and X-ray diffraction measurements (XRD) were performed by using Bruker D8 and Rigaku D/max-2500 diffractometers, respectively, by using the Ka radiation line of copper. The electrical resistivity was measured using the four points van der Pauw method by means of a Quantum Design PPMS-9T with no applied magnetic field and with a small electric current (0.1 mA). Magnetization measurements were carried out by using a commercial SQUID magnetometer from Quantum Design. Magnetization versus temperature data were collected from 5 to 350 K with a heating rate of 5 K/min at 1000 Oe. High-energy resolution fluorescence detected X-ray absorption spectroscopy (HERFD-XANES) measurements were carried out at RT by using a beamline I20-Scanning at Diamond Light Source.

X-ray magnetic circular dichroism (XMCD) measurements were carried out at beamline 4-ID-D of the Advanced Photon Source, Argonne National Laboratory. Measurements were done in a cryomagnet with the sample cooled with 4He vapor. A 500 micron thick diamond phase plate was used to generate circularly polarized X-rays and XMCD measurements were carried out in helicity-switching mode. Measurements were done in fluorescence mode using a grazing incidence geometry and an energy dispersive 4-element Si drift diode detector placed at 90 degrees relative to the incident beam direction. XMCD Data were collected at 10 K with the magnetic fields along and opposite the X-ray propagation direction to remove any artifacts of nonmagnetic origin., Spanish MINECO projects MAT2014-54425-R (MINECO/FEDER, UE), MAT2017-82970-C2-R (AEI/FEDER, UE), MAT2017-83468-R (AEI/FEDER,UE), MAT2017-87134-C02-01-R (AEI/FEDER, UE) and MAT2017-87134-C02-02-R (AEI/FEDER, UE); Spanish MICINN project PID2020-115159GB-I00 / AEI / 10.13039/501100011033; Aragon Regional Government (Projects No. E12-20R and E28-20R); European Union’s Horizon 2020 program Marie Sklodowska-Curie grant agreement no. 665919; European Union’s Horizon 2020 Programme project Quantox of QuantERA ERA-NET Cofund of Quantum Technologies (Grant Agreement No. 731473)., XRD_IrO2_001epitaxy.dat XRD_IrO2_100epitaxy.dat XRD_IrO2_110epitaxy.dat XRD_IrO2_110textured.dat AFM_2d2nm_thick_001epitaxy.tif STEM_5d7_nm_thick_001epitaxy.tif XAS_IrO2_001epitaxy_5d7nm.dat XAS_IrO2_001epitaxy_96nm.dat XAS_IrO2_100epitaxy_1d7nm.dat XAS_IrO2_100epitaxy_5d1nm.dat XAS_IrO2_100epitaxy_89nm.dat XAS_IrO2_110epitaxy_5d3nm.dat XAS_IrO2_110epitaxy_92d2nm.dat XAS_IrO2_polycrystalline_films resistivity_IrO2_ 001epitaxy.dat resistivity_IrO2_ 100epitaxy.dat resistivity_IrO2_ 110epitaxy.dat resistivity_IrO2_ 110texture.dat MvsT_IrO2_001epitaxy_1d5nmthick.dat MvsT_IrO2_100epitaxy_1d5nmthick.dat XAS_XMCD_IrO2_100epitaxy_1d5nmthick.dat XAS_XMCD_powderIrO2.dat XRR_IrO2_5nmthick.dat XRR_IrO2_100nmthick.dat XAS_polycrystalline_vs_amorphous.dat rockingcurves_IrO2.dat RSM_IrO2_001epitaxy_5d7nm.dat RSM_IrO2_001epitaxy_96nm.dat RSM_IrO2_100epitaxy_5d1nm.dat RSM_IrO2_100epitaxy_89nm.dat, Peer reviewed
