11. It is not clear if electron doping generates the same physics as hole doping. Therefore, we shall only consider the case of hole doping, on which much of the experimental activity has been concentrated. For NMR investigations of hole doped cuprates see Imai T., Slichter C.P., Cobb J.L. and Markert J.T., J. Phys. Chem. Solids 56 (1995) 1921-1925, and references therein.
