Abstract

¹³⁹La nuclear quadrupole resonance measurements in lightly doped La₂Cu_1\ensuremath-xLi_xO₄ have been performed to reveal the dependence of the magnetic properties of the antiferromagnetic CuO₂ planes on the character of the doped holes and their interactions with the dopant. A detailed study 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.
