ABSTRACT
This letter reports the effect of distortion of crystal structure on the superconductivity of Y-Ba-Cu-O compounds. The result shows that the cooling rate is responsible for the superconductivity in the range of LN2 temperature with the same composition and heat treatment temperature. The changes of intensity of three dominant x-ray diffraction peaks caused by structural distortion in the perovskite orthorhombic phase may become an important criterion of superconductivity.
