| Abstract: | The Rutherford backscattering (RBS) method has been employed to study the incorporation of oxygen into MgB2 films during their fabrication by pulsed-laser deposition (PLD). A series of MgB2 thin film samples were analyzed, including two films produced in situ on Al2O3 - c substrates (with higher T-c and lower T-c) with an on-axis geometry, one film produced in situ with an off-axis geometry, and one film produced ex situ, with a bulk-like T-c. The amount of oxygen detected by RBS, which is stable in the form of MgO, appears to be correlated with the T-c of the films, the higher the T-c the lower the oxygen content. The superconducting properties of the thin films are discussed in the context of the RBS results. © 2007, Institute of Electrical and Electronics Engineers (IEEE) |
