Mechanism of superconductivity in YBaCuO high Tc oxide superconductors

Present study attempts to explain the attainment of zero resistance in all Y/RE-Ba-Cu-O (123) (RE= rare earth elements) systems of high Tc superconductors along the guide lines of proposed mechanisms for superconductivity in Y-Ba-Cu-O system. In the light of proposed mechanisms attempts have been made to explain some other experimental results of high Te superconductors.
