Abstract

An electrochemical oxidation technique was used to obtain bulk oxidized La2CuO4+δ single crystals from the as-grown crystals. Samples were prepared by galvanostatic oxidation with currents in the range 5–10 μA and with different charging times. Some samples were annealed at 110 °C in flowing oxygen. Small high-quality crystals were obtained from electrochemically oxidized larger crystals that contained microcracks. Transmission x-ray Laue photography and rocking curve measurements for several fundamental diffraction peaks were used to confirm the crystal quality. The Tc and bulk magnetic properties of samples at different stages in the oxidation process are reported. After annealing at 110 °C, a 15 K transition was observed.
