Аннотация: We have successfully synthesized ferromagnetic Fe-In2O 3 nanocomposite thin films for the first time using the thermite reaction Fe2O3 + In = In2O3 + Fe. The initial In/Fe2O3 bilayers were obtained by the deposition of In layers on α-Fe2O3 films. The reaction occurs in a self-propagating mode in a homogeneous thermal film plane field at heating rates above 20 K/s and at temperatures above initiation temperature T[[d]]in[[/d]] ~ 180 °C. At heating rates lower than 20 K/s the mixing of the In and Fe2O3 layers occurs across the whole In/Fe2O3 interface and the synthesis of the ferromagnetic α-Fe phase starts above the initiation temperature T[[d]]in[[/d]] = 180 °C. X-ray diffraction, X-ray photoelectron spectroscopy, Mossbauer spectroscopy, transmission electron microscopy and magnetic measurements were used for phase identification and microstructure observation of the synthesized Fe-In2O3 samples. The reaction products contain (1 1 0) textured α-Fe nanocrystals with a diameter around 100 nm and surrounded by an In2O3 matrix. These results enable new efficient low-temperature methods for synthesizing ferromagnetic nanocomposite films containing ferromagnetic nanoclusters embedded in transparent conducting oxides. © 2014 Elsevier B.V.
