Zusammenfassung:Understanding the transport in ultra-thin epitaxial La0.3Sr0.7MnO3 (LSMO) is a topic widespread current interest. Here we explore electron-electron interactions in low temperature magneto-transport in straight and zigzag nanowires fabricated from ultra-thin epitaxial LSMO films grown to different thicknesses on STO(100) substrates. We find that three-dimensional electron-electron interactions can explain the resistivity upturn, including many of the changes observed with film thickness, nano-patterning, and magnetic field.
