Abstract

We have investigated the oxygen stoichiometry of low-temperature synthesized metastable T'-La2CuO4 bulk samples by neutron scattering. T'-La2CuO4 is the parent compound of electron-doped high-temperature superconductors that is chemically closest to the parent compound of the hole-doped superconductor T-La2CuO4. While usually all electron-doped cuprates require strong reduction to approach stoichiometry, the low-temperature synthesis directly yields fully stoichiometric compounds. This result makes low-temperature grown T'-La2CuO4 the ideal material to perform a comparison of the two parent compounds of hole- and electron-doped cuprates.
