Plasma dynamic synthesis of iron oxides in the «frequency operation» mode of coaxial magnetoplasma accelerator

It is known that the epsilon phase of iron oxide ε-Fe2O3 has the highest value of coercive force among all known simple metal oxides (∼24 kOe) and is characterized by ferromagnetic resonance in the frequency range from 100 to 200 GHz. The noted features determine the possibility of its wide applicat...

Description
Summary:It is known that the epsilon phase of iron oxide ε-Fe2O3 has the highest value of coercive force among all known simple metal oxides (∼24 kOe) and is characterized by ferromagnetic resonance in the frequency range from 100 to 200 GHz. The noted features determine the possibility of its wide application. However, there is the problem of synthesis and stabilization this crystal structure at room temperature. In this paper, we consider the possibility to obtain ε-Fe2O3 by the plasma dynamic method when the system is operating in the frequency (multi-pulse) regime. The influence of the number power supply impulses on the phase composition of the synthesized products was studied using X-ray diffractometry.
