Abstract

Differential scanning calorimetry (DSC) and DC electrical resistivity measurements have been carried out on GdBaCo2O5.5±δ with Ni and Fe substitution at Co lattice site to probe the variation of metal insulator (MI) transition of the parent compound. XRD results show systematic variation in cell parameters with both substitutions implying that both Ni and Fe substitute at Co lattice. Ni strongly alters MI transition whereas Fe shows less influence. It was observed that Ni substitution suppresses the metal insulator transition temperature at the rate of ~5.05K/ at %. Fe substitution does not alter TMI much but diminishes MI transition.
