説明
Cupric oxide superconductors are made of 2D CuO2 sheets and 2D counter sheets stacked alternatively along a crystallographic axis. These sheets match their 2D lattices through intersheet metal-oxygen bonding. Because the Cu-O and counter cation-O bonds should have different compressibilities and different thermal expansion coefficients, it is quite reasonable to assume that preparation in various pressure-temperature regions give us new materials having new structures and/or new compositions.<BR>We found previously that the so-called infinite layer structure could be stabilized at high pressure (6GPa) for a much wider alkaline earth composition range including SrCuO2 than at ambient pressure. Fortunately we recently found a superconductor with Tc-110 K having an alkaline earth deficient composition (Sr, Ca)1-xCuO2 (x-0.1).
