Interface Conduction between Conductive ReO3 Thin Films and NdBa2Cu3O6 Thin Film

The Re oxide films were deposited on quartz glasses by RF reactive sputtering from a Re metal target. The lowest resistivity was observed in the film in-situ annealed at 200 deg. C in Ar atmosphere and showed the order of 10(exp -4) Ohm cm of which the value was still about 10 times as large as that...

Zusammenfassung:	The Re oxide films were deposited on quartz glasses by RF reactive sputtering from a Re metal target. The lowest resistivity was observed in the film in-situ annealed at 200 deg. C in Ar atmosphere and showed the order of 10(exp -4) Ohm cm of which the value was still about 10 times as large as that of a single crystal ReO3. The temperature dependence of the resistivity revealed a metallic behavior A superconductivity did not take place in the bilayered film of ReO3/NdBa2Cu3O6. In the interface region the resistivity minimum probably caused by the Kondo effect was observed in the neighborhood of 120K. This article is from the Mat. Res. Soc.
