The structural and magnetic properties of granular Co–In_2O_3 nanocomposite films formed by vacuum annealing of In/Co_3O_4 film bilayers at a temperature of 550°C have been investigated. The synthesized Co–In_2O_3 films contain ferromagnetic cobalt nanoclusters with an average size of 60 nm and a magnetization of ~340 emu/cm^3 surrounded by the In_2O_3 layer and exhibit the thermally activated conductivity.

“…Co-In 2 O 3 nanocomposites and cobalt-doped In 2 O 3 attract attention due to their possible use in optoelectronic and spintronic devices and gas sensors. [30][31][32][33][34][35][36] The study of the formation processes of Co-In 2 O 3 nanocomposite thin films was carried out directly in the column of a transmission electron microscope (TEM) by heating the film sample of In/Co 3 O 4 from room temperature to 600°C. In situ electron diffraction was used to study the structural transformations during the solid-state reaction.…”

In situ electron diffraction was used to study structural transformations during the formation of Co-In 2 O 3 ferromagnetic nanocomposite thin films in a thermite reaction of In/Co 3 O 4 bilayer thin films. Heating was performed from room temperature to 600°C at a rate of 4°C/min, while simultaneously electron diffraction patterns were recorded at a speed of 4 frames/min. This made it possible to determine the initiation, 185°C, and finishing, 550°C, temperatures of the solid-state synthesis, as well as the change in the phase composition during the thermite reaction. The synthesized Co-In 2 O 3 film nanocomposite contained ferromagnetic cobalt nanoclusters surrounded by an In 2 O 3 layer, with an average size of 20 nm, and had a magnetization of 400 emu/cm 3 and a coercivity of 50 Oe at room temperature. The estimate of the effective interdiffusion coefficient of the reaction suggests that the main mechanism for the formation of the Co-In 2 O 3 nanocomposite is diffusion along the grain boundaries and dislocations.

“…In accord to the micrographs, it is clear that the particles are distributed in homogeneous manner. A MATLAB simulation approach based on the watershed segmentation algorithm [44] is used to evaluate the homogeneity particle distribution. In this algorithm, the first step is to apply distance transform on the binary image of micrograph to generate the distance map.…”

Nanocomposite samples of zinc oxide (ZnO) and indium oxide (In 2 O 3 ) doped with Co (at 1.5% molar concentration) are synthesized through conventional solid-state reaction technique. These samples are taken in a quartz tube and placed in reduction furnace for post-annealing in the presence of hydrogen for~10 h at around 550°C. The X-ray diffraction (XRD) study confirms the formation of hexagonal wurtzite structure for ZnO, Zn H exhibited a perceptible ferromagnetic behavior at 300 K whereas it overturns significantly after long air sintering. An effort has been made to fit the experiential M-H data of hydrogenated samples to the Bound Magnetic Polaron (BMP) model. MATLAB-based simulations have been performed to validate the homogeneity in particle distribution of the samples evinced through SEM micrographs. A multivariate assessment viz. hierarchical cluster analysis is also executed to corroborate and strengthen the experimental findings of magnetic properties.
