Dependence of superconducting transition temperature on doping and structural distortion of the CuO2 planes in La2-xMxCuO4 (M=Nd, Ca, Sr).
By comparing structural and superconducting properties of La2-x-yCaxNdyCuO4 to La2-xSrxCuO4 we have separated the effects of structure and doping on the superconducting Tc. At a fixed doping level, the highest Tc is found for flat and square CuO2 planes in the tetragonal structure. Tc is reduced by...
