The transition-metal perovskites SrFe1-xCoxO3 (0≤x≤1) are of a great interest because the high oxidation states of the transition-metal (Fe(IV), Co(IV)) can be stabilized. Moreover these compounds exhibit interesting magnetic properties. These oxygen stoichiometric phases have been prepared only under high oxygen pressures. A novel preparation method of these phases has been investigated using electrochemical oxidation of the SrFe1-xCoxO2.5 brownmillerite-type compounds [1-3]. The starting materials and the phases obtained after electrochemical processing have been characterized by X-ray powder diffraction, chemical analysis and 57Fe Mössbauer spectroscopy. Finally, the magnetic and transport properties have been studied.< Réduire
