Abstract

Site preference of the partially substituted 3d metal M and superconducting and magnetic properties have been investigated for Pb₂Sr₂Y_{1 - x}Ca_x(Cu_{1 - y}M_y)₃O₈ (M = Fe, Co, Ni, Zn, Ga). It has been found from powder neutron diffraction that Fe atoms preferentially occupy the Cu(1) site in the oxygen-free Cu layer, while Co, Ni, Zn and Ga atoms occupy the Cu(2) site in the CuO₂ layer. From correlation between this site preference of M and the superconducting and magnetic properties, it has been concluded that the partial Cu(1)-site substitution shows little effect on the superconductivity and that there remains antiferromagnetic correlation between Cu²⁺ spins in the Cu(2) site in the normal state even for the high-T_c samples of x = 0.5 with T_c ≈ 80 K.
