Such solution was prepared through a route based on modified polymeric precursor method. Spin-coating deposition on different ceramic substrates was performed and analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The magnetic response of the prepared specimens was studied using a SQUID magnetometer. The obtained results indicated uniform deposition on SrTiO3 and LaAlO3 substrates with similar characteristics. Furthermore, significant differences were detected in the Mn3+/Mn4+ valence ratio and a corresponding diverse magnetic response was observed. The sample prepared on SrTiO3 and LaAlO3 presented a critical temperature around 270 K as expected.217-221engchemical solution depositionPechini methodspin-coatingmagnetic materialArtigo10.1590/S1516-14392011005000036S1516-14392011000200013WOS:000292723200013Acesso abertoS1516-14392011000200013.pdf13538624145320050000-0002-7734-4069
