Abstract
Sr2FeMoO6 film was successfully deposited on LaAlO3 (00l) substrate via chemical solution deposition using low cost precursor materials of Sr nitrate, Fe nitrate, and ammonia-complexed molybdic acid. The X-ray diffraction, field-emission scan electron microscopy and atomic force microscopy results showed that the Sr2FeMoO6 film was highly (00l)-oriented and relatively smooth and dense with few undesired SrMoO4 phase. The transport and magnetic measurements showed that the Sr2FeMoO6 film had a Curie temperature at 368 K and behaved like semiconductors, which could be attributed to the large Fe/Mo disorders. Further works about improving the Fe/Mo order as well as the low-field magnetoresistance are being carried out and will be reported elsewhere.
