ResumoLow-temperature behaviors of the incommensurate superstructure in the recently discovered new oxide superconductor, Bi 2 Sr 2 Ca 1 Cu 2 O 8+δ , are investigated by single-crystal X-ray diffraction. The amplitude of the modulation wave, peak intensities, and widths of the superstructure reflections are independent of temperature in the range from 10 K to room temperature. This implies that the superstructure is not directly associated with the superconductivity.
