The competition between superconductivity (SC) and magnetic order in the Cu02 planes of (La, \_=Gd,)2\_,Sr,Cu,\_,M,04, M =Fe, Zn, Ga and Ni was studied by magnetometry and 57Fe Mossbauer spectroscopy. In the superconducting (x= 0.15-0.2) samples substitution of La by Gd or Cu by Fe causes SC to dis
