Structural and electron transport properties of CaFe2O4 synthesized in air and in helium atmosphere

The samples with the CaFe2O4-type crystal structure were obtained by the solid-state reaction method at 1000 °C in the air and the helium atmosphere for the first time. We investigated the modification of the structural and electronic properties of the obtained samples. Mössbauer, XAFS-, XPS-spectro...
