Abstract
La-139 nuclear quadrupole resonance measurements in lightly doped La2C u1-xLixO4 have been performed to reveal the dependence of the magnetic properties of the antiferromagnetic CuO2 planes on the character of t he doped holes and their interactions with the dopant. A detailed stud y shows that the magnetic properties are remarkably insensitive to the character of the dopant impurity. This indicates that the added holes form previously unrecognized collective structures.
