Anomalous transport properties in superconducting overdoped YBCO thin films

This work is focused on the study of the Fermi Liquid zone, which appears at high doping (overdoped region) in the phase diagram of the high-temperature superconductors. It is generally assumed, without much study, that their behavior in this zone is like a normal metal. Nevertheless, our measurements, and data from other researchers show a different behavior. We present measurements of resistivity and Hall effect in YBaCaCuO thin films. The anomalous properties found are argued to be evidence of a non-Fermi Liquid behavior.
