    Infrared and structural properties of Y1-xNdxBa2Cu3O7-? (0?x?1)
    (Kluwer Academic/Plenum Publ, 2002) Adigüzel, HI; Izgi, T
    Infrared and structural properties of Y1-xNdxBa2Cu3O7-delta (0 less than or equal to x less than or equal to 1) were investigated using infrared absorption spectroscopy and X-ray powder diffraction. The unit cell parameters of the samples were defined using X-ray diffraction data. The resistance measurements showed that the samples revealed superconductivity in the temperature range of 80-100 K. It was observed that by the substitution of Nd to Y in YBa2Cu3O7-delta IR band at 573 cm(-1) that is assigned as Cu-O axial antisymmetric stretching mode shifts to 533 cm-1 while the band at 620 cm-1 that is due to Cu-O symmetric stretching mode in YBa2Cu3O7-delta shifts to 588 cm(-1).
