Physical Properties of HgX Sb1-X Ba2Ca2Cu3O8+δ Superconducting Compound: Effect of Fast Neutrons Irradiation

Applications of superconductor compounds were considered as modern and important topics, especially these which are exposures to one of the nuclear radiation kinds. So, we gone to investigate the influence of fast neutrons irradiation on electrical and structural characteristics of HgxSb1-xBa2Ca2Cu3O8+delta superconducting compound at (x = 0.7) in ratio. The superconducting specimens were synthesized using solid state technique. Specimens were exposure to the nuclear radiation using fast neutrons with doses (0, 9.06 x10(10), 15.3 x 10(10) and 18.17 x 10(10)) n/cm(2) respectively. Electrical and X-ray diffraction properties of superconductor specimens before and after irradiation were investigated under standard conditions. Results of X-ray diffraction show that the structure of HgxSb1-xBa2Ca2Cu3O8+delta has tetragonal structure according to the 1223 phase. Besides, increment of the ratio (c/a) as a result of the effect of fast neutron irradiation. The transition temperature T-c(on) as well as T-c(off)) were decreased from (117 to 85) K and from (133 to 101) K, respectively.
