ON MECHANISM OF OXIDE FORMATION IN ELECTRODEPOSITED CO-BASED FILMS WITH COLUMNAR STRUCTURE

An investigation of the Co oxides formation and distribution dependent on preparation conditions during electrodeposition of hcp Co-based fi lms with perpendicular magnetic anisotropy has been made. It has been shown that the [100] oriented columnar crystallites promote some regul arity in impurity distribution and orientation in the film plane, wher eas the [001] oriented ones- non-regular distribution. Such a behaviou r is associated with the difference in the impurity incorporation for these two cases: preferably crystalline and intergranular, respectivel y, and atomic bonds saturation, and influence on the mechanical and ma gnetic properties of the investigated films.
