A simple low-temperature synthesis method of bismu th ferrite thin films by a wet chemical using bismuth and iron nitrates and two chelating (citric acid and polyvinyl alcohol), is The films were deposited layer by layer on a glass substrate using the dip-coa ting technique. thickness of the layers was controlled b y the of the solutions and withdrawing speed param After specific annealing, in air, the samples ch aracterised by SEM, spectroelipsometry, XPS Raman spectr oscopy. A more thorough control of processing parameters was essential to obtain thin films. Solution chemist ry variations in precursor type) had an impact on the film
