Sažetak
Partial substitution of mercury atoms by bismuth and its influence on the structural, superconducting and magnetic properties of the Hg-based oxide superconductors have been investigated. Two series of samples of the nominal compositions Hg_1-xBi_xBa_2Ca_2Cu_3O_8+delta and Hg_1-xBi_xBa_2Ca_3Cu_4O_10+delta, 0 < x < 0.5, have been prepared by the solid state reactions at normal pressure, by using the sealed quartz tube technique. For the bismuth content range of 0.2 < x < 0.25, for the first series and 0.1 < x < 0.20 for the second one, the formation of the Hg-1234 phase in a high volume percentage, with the superconducting transition Tc(onset) ~ 130 K has been found. The X-ray powder diffraction data and the AC magnetic susceptibility measurements have been correlated.
