Title: Effect of Li 2O on the microstructure, magnetic and transport properties of Tl-2223 superconductor

Here, the present study gives an account of the effect of addition of Li 2O on the ease of phase formation and superconducting properties of Tl 2Ba 2Ca 2Cu 3O 10 + δ (Tl-2223) material. Li 2O slightly decreases the superconducting transition temperature, while an optimal concentration of 20% Li 2O improves the critical current density (J c) by about two fold. We also found substantial effects on the synthesis temperature, microstructure and normal state transport properties of Tl-2223 with Li 2O addition. Short-time annealing under flowing Ar + 4%H 2 (1 h) further improves the superconducting volume fractions, as well as J c.
