Abstract
In this work, a study of magnetic susceptibility of non-superconducting La1 .85Sr0.15(Cu1-xLix)O-4 system with x = 0.08, 0.10, 0.15 and 0.25 was perfor med to characterize the magnetic response of the Cu-O layers, where the dop ed holes are increasingly localized, not only due to disorder effects, but also due to applied magnetic field, indicates that the electronic state of the LSCO matrix evolves towards a spin-singlet ground state.
