PARTIAL EFFECT OF (SRTİO3) NANO ON STRUCTURAL, ELECTRICAL, MAGNETIC CHARACTERISTICS OF SUPERCONDUCTORS COMPOUND YBA2CU3O7-Ó AT HIGH TEMPERATURE DEGREES
Three samples of (YBa2CU3O7-ó) were prepared for the research samples by using – solid interaction status method and annealing method under pressure of 8tan/CM2 ,at temperature 800oC via partial particles compensation of (SrTiO3) Nano in the rates (X=1.5X=1 X=0.5,) of the element Ba . The electrical inspections indicated large increase of critical temperature value Tc, upon compensation of the substance with value X=0.5 for Ba value, whereas critical temperature degree value reached 133k value, but decreased clearly upon compensation of substance X=1 for Ba value, whereas critical temperature degree value Tc reached 102.2K and when the substance compensated with value X=1.5 , improved critical temperature degree value to 122.2K Tc. The formation inspections of rays deviance indicated an obvious existence trapezium structure which existed in the three value in different variations of net distances A,B,C there was obvious increase in C distance . and upon inspections of Sample by FESEM instrument and in amplification rate of 100.00kx---500kx, it was found that granular size rate for the best sample was 33.38 in sample X=0.5 and the images of three samples indicated high accuracy and very detailed and shows makeup formation is bright which was related to light substances and dark areas related to heavy substances. The magnetic inspections indicated through Hystereris curve of the samples and the relationship between magnetic saturation MS and remained magnetic Mr and coerced force Hc and Represent Hystereris circles made-up in superconductors samples complete contrary relation between narrow of circles and improve of critical temperature degree Tc.
