Quantum Corrections in Magnetotransport of BaPbO₃ thin films — •Robert Bartel, Patrick Seiler, Thilo Kopp, and German Hammerl — Experimental Physics VI, Center for Electronic Correlations and Magnetism, Institute of Physics, University of Augsburg, Germany

Recently metallic BaPbO₃ attracted attention as two-dimensional superconductivity was observed in bilayers of insulating BaBiO₃ and BaPbO₃ [1]. Here a detailed study of the transport properties of BaPbO₃ will be presented. Low temperature and magnetic-field dependent measurements of the sheet resistance of BaPbO₃ can be understood in terms of quantum corrections based on disorder, spin-orbit coupling or electron-electron interaction [2].
