Fe2O3, Fe3O4 films have been prepared from Fe(OCH2CH(CH3)(2))(3)-(CH3)(2)CHCH2OH-2.2'-diethanola- mine (DEA)-poly(vinylpyrrolidone) (PVP) solutions by the spin-(SC) and dip-coating (DC) technique on SiO2 and Si substrates. The maximum film thickness achieved without crack formation has been increased by incorporation of PVP (relative molecular weights 40000 and 360000) into the precursor solution. The stability of the precursor solutions was remarkably increased by addition of DEA. Higher-molecular-weight PVP has been more effective in increasing the thickness. The minimum concentration of DEA, which results in pronounced increase of solutions stability, is about R-P (n(DEA)/n(Fe) = 0.1). Microstructure, surface morphology, and magnetic properties of the films have been also investigated using SEM, AFM, and SQUID, respectively.
