摘要：

The phase separation behavior of superconducting cuprate systems is studied. Using experimental data obtained from electrical resistivity and susceptibility measurements on La2CuO4+delta we demonstrate that the phase separation is of electronic and percolative nature. In addition, the experiments clearly prove the coexistence of bulk superconductivity and long-range antiferromagnetic (afm) order.
