STUDY OF THE EFFECT OF LASER IRRADIATION ON THE ELECTRICAL AND STRUCTURAL PROPERTIES OF PB2-XHGXBA2-Y SRY CA2 CU3 O10+Δ SUPERCONDUCTING AT COMPENSATION RATIOS Y= (0.1,0.2,0.3,0.4)
Superconducting compound Pb2-xHgxBa2-ySry Ca2 Cu3 O10+δ was pressurized (8 tons) using a hydraulic press for different compensation ratios x=(0-0.1-0.2-0.3-0.4./cm2). The prepared sample was put into an electric furnace, and the temperature was raised from room temperature to (600°C) at a rate of (120°C/h), and then the sample was kept at this temperature for (12) hours, and then the furnace temperature was increased at (120°C/h) h) from (600 °C) to (800 °C) and maintained at this level (24 h) in an oxygen-saturated atmosphere and then at a rate of (30 °C/h) from (800 °C) down to (600 °C) and hold at that temperature for (12) hours، Thereafter, the temperature was lowered from (600° C.) to room temperature at a rate of (30° C./h), and when the synthesis of the compound was completed in X-ray diffraction XRD, laser light was irradiated. Experiments have shown that the results before laser exposure are best compensated. The ratio is x=0. If the compensation ratio of Y is increased to 0.2, its value and regularity increase with the size (c), a = b = 5.471 (A°), c = 34.683 (A°). The increased regularity we observed in the crystal structure of the compound, the compound played better in the crystal structure.Whereas after irradiating and increasing the scale and increasing the compensation ratio to 0.2, the value and regularity increase with increasing dimensionality (c) a = b = 5.479 (A°), c = 34.731 (A°) we note a If we increase the compensation percentage and make the compound play better in the crystal structure, we can improve the regularity of the crystal structure of the compound.Checking the electrical properties of the resistance test, the results show that when the compensation ratio also increases the critical temperature of the junction, the optimal compensation ratio before laser irradiation is x = 0.2, so the critical temperature is (K135). This result can explain that the compound plays an important role in the structure and crystal structure, but the critical temperature after
