Abstract

This paper reports some preliminary results obtained on the effect of Fe, Co, Zn substitution on the thermal expansion of high T_c superconducting compounds Gd₁Ba₂(Cu_1-xM _x)₃O₇, M=Fe, Co, Zn for 0≤x≤ 2%. All the samples are single phased. The pure sample exhibited a jump of about 6.9×10^-8 per Kelvin. It is observed that the jump in thermal expansion increases for dopants occupying Cu(1) sites, whereas for dopants which occupy Cu(2) sites, a decrease in jump in thermal expansion is observed.
