アブストラクト

We study the epitaxial structure and physical properties of B-site-ordered Sr2TiRuO6 double-perovskite films by pulsed-laser deposition. TheTi/Ru order was evaluated (up to 67%) from intensity profiles of the out-of-plane reflections measured using a synchrotron-light source. Theelectronic states were investigated as a function of the Ti/Ru order. A systematic increase in resistivity with the Ti/Ru order was observed, whichis associated with the localization behavior of Ru 4d electrons as verified by photoemission spectroscopy. These results suggest that theelectronic properties of Sr₂TiRuO₆ are strongly influenced by the 4d state connectivity between neighboring Ru atoms.
