Influence of transition metals substitution on the superconductor Bi4Ca3Sr3Cu4Oy

  • 1. Tata Inst. of Fundamental Research, Bombay (India)

Description

The results of investigation on the specimens Bi4Ca3Sr3Cusub(4-x)TxOy (T=Fe, Co, Ni, x≤0.5) synthesized in air are presented. Fe and Co substituents result in the formation of Bi2Sr2CuOy- type of phase, with considerable depression of Tc of the main phase. However, Ni is completely soluble with Cu in this concentration range without significant depression of superconducting transition temperature (Tc). This difference in the solubility behaviour of Fe and Co on the one hand and Ni on the other is explained taking into account ionic charge and coordination number mismatches.
