Abstract

The structural and magnetic properties of CoPt-In₂O₃ nanocomposite films formed by vacuum annealing of the In/(Co3O4 + Pt)/MgO film system in the temperature range of 100–800 ◦C have been investigated. The synthesized nanocomposite films contain ferromagnetic CoPt grains with an average size of 5nm enclosed in an In2O3 matrix, and have a magnetization of 600 emu/cm3, and a coercivity of 150 Oe at room temperature. The initiation 200 ◦C and finishing 800 ◦C temperatures of synthesis were determined, as well as the change in the phase composition of the In/(Co3O4 + Pt)/MgO film during vacuum annealing
