Characterization of nano-oxide layers fabricated by ion beam oxidation [PDF]

open access: yes, 2002
In this paper, a remote O2 ion source is used for the formation of nano-oxide layers. The oxidation efficiency was measured in CoFe-oxide films, and a decrease of the oxide layer with the pan angle and the oxidation pressure is observed.
