Abstract:
The structural and magnetic properties of granular Co–In$_{2}$O$_{3}$ nanocomposite films formed by vacuum annealing of In/Co$_3$O$_4$ film bilayers at a temperature of 550$^{\circ}$C have been investigated. The synthesized Co–In$_{2}$O$_{3}$ films contain ferromagnetic cobalt nanoclusters with an average size of 60 nm and a magnetization of $\sim$340 emu/cm$^3$ surrounded by the In$_2$O$_3$ layer and exhibit the thermally activated conductivity.
