Abstract:

High velocity resolution Mossbauer spectroscopy was used to study of (CuFe(2)O(4))(1-x) (SnO(2))(x) nanocomposites (x = 0, 1, 5, 10, 20 wt.\%). Mossbauer spectra were measured at room temperature with registration in 4,096 channels and further presentation in 1,024 channels. Mossbauer spectra of CuFe(2)O(4) and (CuFe(2)O(4))(0.99) + (SnO(2))(0.01) were better fitted using three sextets while spectra of (CuFe(2)O(4))(0.95) + (SnO(2))(0.05) and (CuFe(2)O(4))(0.80) + (SnO(2))(0.20) were better fitted using four sextets and one doublet. In contrast, spectrum of (CuFe(2)O(4))(0.80) + (SnO(2))(0.20) was better fitted using five sextets and one doublet. Mossbauer 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 (CuFe(2)O(4))(0.80) + (SnO(2))(0.20) was supposed.
