Commensurate dynamic magnetic correlations in La2(Cu,Li)O4

Abstract

When sufficient numbers of holes are introduced into the two-dimensional CuO2 square lattice, dynamic magnetic correlations become incommensurate with underlying lattice in all previously investigated La_{2-x}A_xCu_{1-z}B_zO_{4+y} (A=Sr or Nd, B=Zn) including high T_C superconductors and insulators, and in bilayered superconducting YBa_2Cu_3O_{6.6} and Bi_2Sr_2CaCu_2O_8. Magnetic correlations also become incommensurate in structurally related La_2NiO_4 when doped with Sr or O. We report an exception to this so-far well established experimental "rule" in La_2Cu_{1-z}Li_{z}O_4 in which magnetic correlations remain commensurate.
