The Role of Cooling Condition on the Superconducting Properties of Tl2-xHgxSr2Ca2Cu3O10+δ System
Solid state reaction method was used to prepare high temperature superconductor with a nominal composition Tl2-xHgxSr2Ca2Cu3O10+δ (0 ≤ x ≤ 1). The effect of quenching on the superconducting properties has been investigated by preparing two sets of samples at 1133 K for 3 hrs. The superconducting properties of the samples have been examined by electrical measurements. It is found that a partial substitution for Tl by Hg increases the formation of high-Tc phase and increases its Tc. X-ray diffraction (XRD) pattern analyses have shown a tetragonal structure, and there are at least two superconducting phases.
