In the electron-doped cuprates, on the other hand, superconductivity appears only in a narrow range of high electron concentration ($\\sim$ doped Ce content) after reduction annealing, and strong antiferromagnetic (AFM) correlation persists in the superconducting phase. Recently, Pr$_{1.3-x}$La$_{0.7}$Ce$_{x}$CuO$_{4}$ (PLCCO) bulk single crystals annealed by a \"protect annealing\" method showed a high $T_c$ of $\\sim$ 27 K for small Ce content down to $x \\sim 0.05$.
