Investigation the Crystalline Size and Strain of Perovskite (YBa2Cu3O6+?) by variant method

Abstract

The Perovskite compound of YBa2Cu3O6_+? ,in this study was prepared by method of pulsed laser deposition (PLD) on substrate of quartz. The diffraction ofX-RAY was studied on the nature of crystalline of the compound YBa₂Cu₃O_{6 +?} , the results showed Crystal system tetragonal structures. The Full width at half maximum (FWHM) was calculated by the Orange Pro program by using X-RAY data. The crystalline size and stress were calculated by Scherrer, Willeamson-Heall, size-strain-plot and Healder-Wgner methods, Where the average of crystalline size and stress (65.66 nm, 5.827X 10^-3), respectively.
