X-ray diffraction (XRD) was used to study the crystal structure of the films. The XRD patterns showed that the films grown at the pH levels of 3.70 and 3.30 have a mixed phase consisting of face-centred cubic (fcc) and body-centred cubic, while those grown at pH=2.90 have only fcc structure. It was observed that the film composition, by energy dispersive x-ray spectroscopy, contain around 88 at% Co and 12 at% Fe for all films investigated in this study. Morphological observations indicated that all films have grainy structure with the slight change of grain size depending on the electrolyte pH. Magnetoresistance measurements, made at room temperature, showed that all films exhibited anisotropic magnetoresistance, which is affected by the electrolyte pH. From the magnetic measurements made by vibrating sample magnetometer, the saturation magnetization increases as the electrolyte pH decreases. Furthermore, all films have in-plane easy-axis direction of magnetization.eninfo:eu-repo/semantics/closedAccessElectrodepositionCo-Fe filmXRDAMRMagnetic propertyMagnetoresistanceAlloysMaterials sciencePhysicsCrystal structureElectric resistanceElectrodepositionElectrolysisElectrolytesMagnetic field effectsMagnetic propertiesMagnetoelectronicsMagnetoresistanceMetallic filmsSaturation magnetizationTitaniumWater metersX ray diffractionX ray spectroscopyAMRAnisotropic magnetoresistanceBody-centred cubicEnergy dispersive X ray spectroscopyFace-centred cubicFcc structuresFe filmsFilm compositionGrain sizeGrainy structuresIn-planeMagnetic measurementsMagnetoresistance measurementsMixed phaseMorphological observationsPH levelsPolycrystalline titaniumRoom temperatureStructural and magnetic propertiesVibrating sample magnetometeRXRDXRD patternsCobaltArticle0002757461000152-s2.0-77949306428109510973229-12Materials science, multidisciplinaryPhysics, condensed matterElectroplating; Cobalt Alloys; Magnetic Properties
