Growth of oxygen adlayer on a Ru(0001) surface with high energy supersonic oxygen molecular beam was studied using high energy resolution X-ray photoelectron spectroscopy. The Ru 3
core level was used to monitor the growth of oxygen adlayer in the coverage region from 0.5 to 0.6 monolayer (ML) and the photoelectron spectrum was resolved into bulk and two surface components denoted as S1(2O) and S1(3O), which were first layer Ru atoms bonded to two and three oxygen atoms, respectively. The intensity change of each component as a function of oxygen dosage suggests the possibility of partial island formation on Ru(0001).

The multilayer structure is essential for the important magnetic-recording devices such as a read head, a magnetic and a magneto optical recording media and so on. In the multilayers the function of magnetic devices is strongly influenced by the interfacial magnetic structures and mixing of atoms at the interface as well as crystalline of each layer itself. Polarized neutron reflectometry is the most powerful and non-destructive way to investigate such buried internal magnetic structure. In this article a feasibility study of domain distribution in multilayers designed for magnetic read heads is reported.
