Structural investigations of high temperature superconductorsX-ray investigation revealed the {100}/<110> twin parameters for La2-xSrxCuO4 (x< 0. 2 and {110}/<110>for YBa2Cu3O7-x. The twin boundaries were found to be not monoatomic planes. They represent transitional regions wherein the ...
Investigation on a high-T-c superconductor, La1.85Sr0.15CuO4, was performed in the wide range of Q-E space by means of neutron scattering and synchrotron radiation. The structure as well as the phonon dynamics showed a clear evolution at T-c. We found a spontaneous strain and phonon soften...
摘要: SINCE the discovery of high-Tc superconductors, experiments have revealed that the phase diagrams of La2-xSrxCuO4 and YBa2Cu3O6+x resemble each other. The antiferromagnetic phase is commonly situated in the vicinity of the superconductive phase. In Bi-2212 sys-......
The comprehensive investigation of oxypnictide materials by the solid-state chemistry community began in recent years only. The first comprehensive review on pnictide oxides was published in 1995 by Kauzlarich and co-authors [7], summarizing the data available at that time for around 30 known co...
