**Please note that the full text is embargoed** ABSTRACT: Giant resistance switching behavior in mixed conductive LaBaCo2O5+ epitaxial thin film were
discovered in high temperature and reducing environments during the reduction and reoxidation
process. A reproducible resistance response of over 99% was achieved in the films during a change
of 4% H2 /96% N2 to oxygen at temperature range of 400– 780 °C. The results indicate that at,
low oxygen partial pressure, the extension of oxygen deficiency is an essential factor to the high
temperature physical properties of LaBaCo2O5+ and demonstrates its potential application as a
chemical sensor device for reducing environments at high temperature. © 2010 American Institute
