Infrared and Structural Properties of Y1−xNdxBa2Cu3O7−δ (0 ≤ x ≤ 1)

Infrared and structural properties of Y1−xNdxBa2Cu3O7−δ (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 − δ 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−δ shifts to 588 cm−1.
