Investigation of physical and structural properties of cs doped y1ba2cu3o7 superconductors

In this work, YBa2‑xCsxCu3O7‑δ (x= 0.05, 0.1, 0.2 and 0.3 wt. %) samples were prepared by using solid state reaction method. Some electrical, physical structural properties of these compounds examined SEM (scanning electron microscopy), XRD (X-ray diffraction), electrical resistivity, critical current density AC susceptibility measurements, respectively. On the basis it would seem that increasing amount Cs doping, porous structures decrease grain size increases up to approximately 50 μm. Unit cell parameters calculated employing measurements. data obtained from X-ray diffraction, atoms displaced Ba in crystal structure. From measurements resistivity at 80 K-120 K temperature, was determined highest transition temperature 91.5 after addition 0.05 % Cs. The decreased doping. Critical on same showed as doping increases, values Jc decrease. magnetic a sharper superconducting wt.%) with increase additive amount.
