Abstract
We review recent work on La2Cu 1-x Li x O 4 for 0 < x < 0.5. Li substitutes for Cu in La2CuO4 , resulting in both the addition of a hole and the loss of a spin (because Li is monovalent and S = 0 while Cu is divalent and S = 1/2). Qualitatively, Li substitution has the same effect as the combined substitution of Sr and Zn. We explore the extent to which this analogy can be made quantitative and discuss how these results influence our understanding of the doped hole state in La2CuO4 .
