    • Recently, a crystal of (Formula presented) showing bulk superconductivity above (Formula presented) 80 K was synthesized by Zou et al. using the traveling-solvent floating-zone method [Zhigang Zou, Kunihiki Oka, Toshimitsu Ito, and Yoshikazu Nishihara, Jpn. J. Appl. Phys. 36, L18 (1997)]. This result is in sharp contrast to the nonsuperconducting crystal Y(Formula presented)Pr(Formula presented)Ba(Formula presented)Cu(Formula presented)O(Formula presented) with (Formula presented) 0.56 synthesized by the typical slow cooling method. This may be due to due to the lack of the charge carriers in (Formula presented) planes. According to the X-ray diffraction analysis by Zou et al., there is no particular difference in the structures between these two crystals. Thus, it is inferred that the superconductivity of (Formula presented) originates from the local crystallographic change which causes the charge carriers to exist in (Formula presented) planes. At this point, to elucidate the characteristics of the local change more detailed experiments are needed.
