It is observed that the crystal structure of the films converts from hexagonal close-packed (hcp) to a mixed phase of face centered cubic and hcp as the electrolyte pH decreases. The grain size calculated from the X-ray diffraction patterns decreases with the decrease of electrolyte pH. The surface of the films grown at a high pH is more uniform than that of the films grown at a low pH. The saturation magnetization and the coercivity decrease as the electrolyte pH decreases. The high coercivity value at high pH corresponds to the hcp crystal structure of the films as well as the large grain size of Co clusters. Magnetic measurements also reveal that the easy axis direction of magnetization is parallel to the film plane for all films since the higher remanent magnetization and lower saturation field are observed in parallel hysteresis loops.eninfo:eu-repo/semantics/closedAccessPhysicsCobalt filmsCrystal structureElectrodepositionMagnetic propertiesGrain sizeThin filmsCoercivityCobalt compoundsCoercive forceCrystal structureDiffractionElectrodepositionElectrolytesGrain size and shapeHysteresis loopsMagnetic materialsSaturation magnetizationX ray diffractionCo clustersCobalt filmEasy axisElectrodeposited cobaltFace-centered cubicFilm planesGrain sizeHexagonal close-packedHigh coercivityHigh pHLarge-grainMixed phasepH valuePolycrystalline copperRemanent magnetizationSaturation fieldsCobaltElectrodeposited cobalt films: Alteration caused by the electrolyte pHArticle0002898557001332-s2.0-80052169139801804241-2Physics, appliedPhysics, condensed matterElectroplating; Cobalt Alloys; Magnetic Properties
