Composition, structure, magnetic and luminescent properties of EuFeO3/TiO2/Ti composites fabricated by combination of plasma electrolytic oxidation and extraction pyrolysis

Layered oxide coatings containing europium ferrite multiferroic have been synthesized on titanium plates. With the presence of EuFeO3, the composite acquires weak ferromagnetic properties: the coercive force attains 45-78 Oe in the temperature range 3-340 K. The magnetic properties of EuFeO3/TiO2/Ti composites are different from those of nanosized EuFeO3 powder obtained by extraction pyrolysis. It has been established that EuFeO3/TiO2/Ti composites have luminescence properties characteristic of inorganic materials with europium ions. The obtained data assume that the deposited layer containing EuFeO3 can have a complex structure: both oxidized and reduced elements may be present in its composition.
