Abstract:
In this work, we studied the effect of type of substrates, thickness and annealing temperature on morphological, structural, electrical and magnetic properties of Co-based (Co-Cu and Co-Cr) and Co-doped BiFeO3 films. Co-Cu films prepared on different flexible substrates showed that the magnetic properties and crystallinity of sputtered Co-Cu films were obviously modified by surface morphology and crystallinity of the substrate and amorphous phase of substrate significantly improved the magnetic properties of Co-Cu film. Co-Cr films with different thickness were deposited on glass substrate and then heat treated at 600o C in an argon atmosphere. The as-deposited film was composed of the CoCr, CoO and amorphous structure phases. After heat treatment, Co, Cr, Co3O4, Cr2O3 and CoCr2O4 phases were occurred. The heat treatment and thickness supported the perpendicular magnetic anisotropy and enhanced the magnetic properties of the sputtered Co-Cr film by virtual of the manipulation of the film structure, chemical composition and grain dispersion. Sputtered BiFeO3/Co bilayer film was deposited on glass substrate with heat treatment at temperatures of 100°C, 200°C and 300°C. It was found that 300°C-film showed that BiFeO3 perovskite structure with coral-like morphology and lowest Bi/Fe ratio about 1.2 and also possessed the highest ferromagnetic phase. The results confirmed that the ferromagnetic phase of the film was sufficiently induced by low annealing temperature at 300o C in order to diffuse Co atoms into BiFeO3 layer.
