- Abstract
High velocity resolution Mössbauer spectroscopy was used to study of (CuFe2O4)1 − x (SnO2) x nanocomposites ( x = 0, 1, 5, 10, 20 wt.%). Mössbauer spectra were measured at room temperature with registration in 4,096 channels and further presentation in 1,024 channels. Mössbauer spectra of CuFe2O4 and (CuFe2O4)0.99 + (SnO2)0.01 were better fitted using three sextets while spectra of (CuFe2O4)0.95 + (SnO2)0.05 and (CuFe2O4)0.80 + (SnO2)0.20 were better fitted using four sextets and one doublet. In contrast, spectrum of (CuFe2O4)0.80 + (SnO2)0.20 was better fitted using five sextets and one doublet. Mössbauer hyperfine parameters were related to octahedral and tetrahedral sites in copper ferrites. The presence of two different tetrahedral sites in studied ferrites and two different octahedral sites in (CuFe2O4)0.80 + (SnO2)0.20 was supposed.
