Abstract
Cupric-oxide superconductors are complex oxides involving counter cations like rare-earth and alkaline-earth ions. Counter cations and cupric ions compromise with each other to coexist in a crystal by adjusting their coordination numbers, bond lengths, and bond angles. Pressure and temperature evidently influence these parameters, and so, depending upon pressure and temperature, different compositions would be stabilized in a given structure and different structures would appear for a given composition. By applying 6GPa to the alkaline-earth-copper-oxygen system a new superconductor family with the highest T c of 110K has been found.
