Abstract

Influence of oxygen and water vapor in vacuum chamber during the deposition process of (Co40Fe40B20)x(LiNbO3)100-x thin film nanocomposites on electrical properties has been investigated. A significant growth in the electrical resistivity of (Co40Fe40B20)x(LiNbO3)100-x nanocomposites has been established with an increase in reactive gases partial pressure (oxygen and water vapor). It has been found, that the recrystallization temperature of composites deposited in argon atmosphere also increases with metallic phase concentration. While the recrystallization temperature of (Co40Fe40B20)x(LiNbO3)100-x nanocomposites sinthesized in mixed atmosphere of Ar with the reactive gases (oxygen or water vapor) decreases due to increase of the heterogeneous structure oxidation.
