Abstract

The competition between superconductivity (SC) and magnetic order in the CuO₂ planes of (La_1-zGd_z)_2-xSr_xCu_1-yM_yO₄, M=Fe, Zn, Ga and Ni was studied by magnetometry and ⁵⁷Fe Mössbauer spectroscopy. In the superconducting (x=0.15-0.2) samples substitution of La by Gd or Cu by Fe causes SC to disappear and magnetic order at T_N=13 K to be formed. On the other hand, substitution in the CuO₂ planes by Zn, Ga or Ni suppresses SC andinhibits magnetic order in the plane. This behavior is similar to that found in Y_1-xPr_xBa₂(Cu_1-yM_y)₃O_z.
