【Abstract】 Since the single-phase YBa₂ Cu₃O_7-y has perovskite structure, therefore compounds which constitute the perovskite structure can be expectative high temperature superconductive materials. In this paper, we have studied the quaternary oxide compounds and fluoride compounds, which constitute the perovskite structure, by means of pattern recognition and many possible high T_c superconductors are predicted. The superconductive mechanism has been discussed by using the characteristics of six bond-parameters.更多还原
