Abstract High velocity resolution M�ossbauer spectroscopy was used to study of (CuFe2O4)1−x(SnO2)x nanocomposites (x = 0, 1, 5, 10, 20 wt.%). M�ossbauer spectra were measured at room temperature with registration in 4,096 channels and further presentation in 1,024 channels. M�ossbauer 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. M�ossbauer 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.
