Abstract
Mn/acetylacetone chelate was synthesized using Mn(CH3COO)2·4H2O as raw material, methanol as the solvent, and acetylacetone as the chelating agent. The ultraviolet (UV)-absorption peak of the synthesized chelate was found around 298 nm. CaMn7O12 sol was subsequently prepared using the Mn/AcAc chelate as the Mn source and calcium nitrate as the calcium source. The UV test indicates that the CaMn7O12 sol has the UV-sensitive characteristics. Owing to its photo-sensitivity, micro-patterned CaMn7O12 ceramic film can be prepared without photoresist, only through dip-coating, drying, UV-irradiation, solvent-washing, and heat treatment. The magnetic test result indicates that the micro-patterned CaMn7O12 ceramic film has a saturation magnetization of 112.8 emu/cm3, which is close to that of non-patterned CaMn7O12 ceramic film.
