Replacement study of thallium by Zn and Ni in Tl-1223 superconductor phase

摘要

Preparation, characterization and investigation of (Tl1-xMx)Ba2Ca2Cu3O9-delta, where M = Zn and Ni with 0 less than or equal to x less than or equal to 0.6, are performed. Our results show that the transition temperature "T-c" increases up to x = 0.2 for Zn substitution samples whereas it decreases with increasing Ni content. [References: 5]
