Study Effect of annealing Temperature on enhancement of High-Tc Phase for BiPbSrCaCuZnO thin film through thermal expantion

suzan malek, suzan malek shakouli


Annealing thermal plays an important role on the formation of high Tc-phase BiPbSrCaCuZnO through expansion and contraction layers which be associated with formation high and low phases respectively, The prepared samples composition BiPbSrCaCuZnO have been annealed at (820,840,860,880) C°.
It is observed the critical temperature Tc increase for films which annealed at (820,840,880) C°while Tc decreases at Ta =860 C°.
