Abstract The electronic specific heat Cel was studied in Ga- and Zn-doped La2−xSrxCuO4 (0.16≤x≤0.22) at T≤10K. Partial substitution of Ga or Zn for Cu suppresses Tc and revives the T-linear electronic specific heat, γT, markedly. The γ(y)/γn vs Tc/Tc0 relation for Zn-doped samples with x≥0.2 is in good agreement with the theoretical one for resonant impurity scattering in a d-wave superconductor, while those for Ga-doped samples and for Zn-doped samples with x ≤ 0.2 deviate slightly from the theoretical curve. The deviation will be discussed in relation to changes in the magnetic properties of 3d electrons.
