Magnetism and Electrical Conduction in Lightly-Doped Single-Layer High- T c Cuprate La 2 CuO 4+ δ

The temperature dependences of magnetization and electrical resistivity as well as their magnetic field dependences have been examined in lightly-doped single-layer cuprate La 2 CuO 4+ δ [LCO, hole-doping level p(2δ) ≅ 0.03] single crystals, in comparison with those in the extrem...

Suppression of spectral gap and flat bands on a cuprate superconductor side-surface

Abstract Side surfaces of cuprate superconductors are expected to display a suppressed d -wave order parameter and zero-energy topological flat bands with a large density of states, making them susceptible to symmetry broken orders. Yet such surfaces have never been investigated...
