Abstract :

In the present paper, we have prepared samples of high temperature superconductors namely Tl2-xAgxSr2-BayCa2Cu3O10+& using solid state reaction, and nano-technique for different concentration of (x, y=0.1 0.2, 0.3, 0.4, 0.5) and compressing by hydraulic at 8 ton/cm2 also annealing samples at 850Ã?Â?C. The samples have been characterized resistivity measurements using the electrical resistively measurement. At x, y=0.3 ratio of Ag, Be give a best value of Tc=142 K. The morphology of the samples obtained by AFM in three dimensions views four samples after annealing treatment. Also give a best Nano size value is 94.74 nm at x, y=0.3. The structure of surface morphology of the samples was studied by SEM. The results of EDX image demonstrated that there is not unwanted element.
