PURPOSE:A laminar perovskite oxide known as an insulator containing Ca, Sr, Cr, etc., is utilized as a superconductor. CONSTITUTION:A laminar perovskite oxide 3 expressed by Ca1-aSraCuO2+y (0<=a<=1; -1<=y<=1), Sr2-bCabCuCl2O2+y (0<=b<=2), Ca3-cSrcCu2Cl2O4+y (0<=c<=3), (Ca1-xREx)1-dSrdCuO2+y (RE is at least one kind of element selected from rare- earth element; 0<d<1; 0<x<1), etc., is combined with a high-pressure apparatus to apply high pressure to the oxide. The above oxide gest superconductivity by the application of high pressure with the high-pressure apparatus. |
