Temperature Dependent XAFS Study of CrFe2O4
Keywords:Thermoelectric material, Metal oxide, Absorption spectroscopy, Transition metal
CrFe2O4 (CFO) is a multifunctional magnetic, optoelectronic, and energy conversion material with research interest of current technology. The aim of the study was to test the CFO material against heat treatment and to analyze the electronic and crystal response when the material exposed to heat. To this aim, crystal and electronic properties of CFO material were investigated by x-ray absorption fine structure (XAFS) spectroscopy technique calculations for temperatures of 300, 373, 423, 473, 523, and 573 K. According to increasing the temperature, not so high reaction has been determined in Fe coordination. However, Cr atom has been affected by the temperature more than the Fe atoms. The obtained data at 523 K have been found the most fascinating for analysis.
