Class 13, Local structure and structural effects in cuprates
Right: (La,M)2CuO4 superconducting Tc: Composition dependence at 10 K of (a) the in-planecopper-oxygen, Cu-O(1), bond lengths; (b) the orthorhombic strain; (c) the Cu-O(1)-Cu bond angles; (d ) the superconducting Tc’s for La2–
xSrxCuO4 and La2–xCaxCuO4 systems. Tetragonal La2–xSrxCuO4 systems under applied pressure are marked by solid squares.
