抜粋

The effects of non-magnetic Zn and magnetic Ni substitution for Cu site on magnetism are studied by measurements of uniform magnetic susceptibility for lightly doped La2-xSrxCu1-zMzO4 (M = Zn or Ni) polycrystalline samples. For the parent x = 0, Zn doping suppresses the Néel temperature TN whereas Ni doping hardly changes TN up to z = 0.3. For the lightly doped samples with TN ∼ 0, the Ni doping recovers TN. For the superconducting samples, the Ni doping induces the superconductivity-to-antiferromagnetic transition (or crossover). All the heavily Ni doped samples indicate a spin glass behavior at ∼15 K.
