摘要：
In this paper, the effect of thickness on the structural, optical, and magnetic properties of the BiFeO3 (BFO) thin films formed on a glass substrate by the chemical solution deposition has been studied. The sol-gel method combined by the spin-coating technique is used to fabricate BFO thin films. The XRD analysis indicated that BFO thin films had a rhombohedral perovskite structure. Polycrystallinity, smooth and compact surface morphology, and uniform size distribution, as well as average thickness of layers, were observed in FESEM images. UV-vis spectra showed that the absorption coefficient and energy bandgap increased by increasing the thickness of films. VSM measurements indicated that the thin films showed a behavior between weak ferromagnetic and anti-ferromagnetism for all samples.
