Öğe Infrared and Structural Properties of Y1-xNdxBa2Cu3O7-? (0 < x < 1)(2002) Adigüzel H.I.; Izgi T.Infrared and structural properties of Y1-xNdxBa2Cu3O7-? (0 < x < 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-? 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-? shifts to 588 cm-1. ©2002 Plenum Publishing Corporation.
