Query: Anisotropic Magnetoresistance in Lightly Doped La_{2-x}Sr_{x}CuO_{4}:
  Impact of Anti-Phase Domain Boundaries on the Electron Transport   Detailed behavior of the magnetoresistance (MR) is studied in lightly doped
antiferromagnetic La_{1.99}Sr_{0.01}CuO_{4}, where, thanks to the weak
ferromagnetic moment due to spin canting, the antiferromagnetic (AF) domain
structure can be manipulated by the magnetic field. The MR behavior
demonstrates that CuO_2 planes indeed contain anti-phase AF domain boundaries
in which charges are confined, forming anti-phase stripes. The data suggest
that a high magnetic field turns the anti-phase stripes into in-phase stripes,
and the latter appear to give better conduction than the former, which
challenges the notion that the anti-phase character of stripes facilitates
charge motion.
