Evidence of apical oxygen in Nd2CuOy determined by single-crystal neutron diffraction

Autor: Radaelli, PG, Jorgensen, JD, Schultz, AJ, Peng, JL, Greene, RL

The defect structure of oxygenated and reduced Nd2CuOy (y4) was investigated by single-crystal neutron diffraction. Structural refinements indicate the presence of interstitial oxygen atoms in the apical O(3) position, directly above or below the cop

Structural and superconducting properties of La2-xSrxCuO4 as a function of Sr content

Autor: Radaelli, PG, Hinks, DG, Mitchell, AW, Hunter, BA, Wagner, JL, Dabrowski, B, Vandervoort, KG, Viswanathan, HK, Jorgensen, JD

We have studied the structural and superconducting properties of La2-xSrxCuO4 by neutron and x-ray powder diffraction, thermogravimetry, ac susceptibility, and dc magnetization. The kinetics of the synthesis reaction were studied in order to determin

Structure of the superconducting La2CuO4+δ phases (δ0.08,0.12) prepared by electrochemical oxidation

Autor: Radaelli, PG, Jorgensen, JD, Schultz, AJ, Hunter, BA, Wagner, JL, Chou, FC, Johnston, DC

Two powder samples of electrochemically oxidized La2CuO4+δ (nominally δ0.08 and 0.12) and one single crystal (δ0.1), with superconducting critical temperatures of 32, 42, and 40 K, respectively, were studied using neutron diffraction. All samples
