What is Features of structural fluctuations in superconducting oxides LnCeCuO (Ln Pr, Nd) about?
Features of both crystal structures and structural fluctuations in superconducting oxides, Ln2\_xCexCuO4\_y (Ln = Pr, Nd) with 0-< x < 0.20, have been examined in detail by means of electron diffraction. In electron diffraction patterns of Ln2\_~CexCuO4\_y (Ln = Pr, Nd), there commonly exists characteristic diffuse scattering in addition to fundamental spots due to the T'-structure. The diffuse scattering is observed as a spike shape along the ( 1 1 0) directions around the fundamental spot. Because of no temperature dependence of the intensity of the scattering, the scattering is understood to be mainly due to static displacements of atoms. In addition, the electron-beam irradiation results in two effects in diffraction patterns. One is characterized by the appearance of supertattice spots in both Nd2\_xCexCuO4\_y and Pr2\_~CexCuO4\_r That is, the irradiation produces the modulated structure due to the ordering of oxygen vacancies. The other is the splitting of the fundamental spot in Prz\_xCexCuO4\_r, which is due to a twinning resulting from a structural transition.
