| Description |
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.
