Popis: We studied the effect of Sn substitution in a new mercury-based superconductor with nominal composition . At this stage of investigation the material is multiphasic with dominating superconducting phases up to x = 0.3. It was established that Sn stimulates the formation of the Hg-1212 phase and enhances the diamagnetic volume fraction but also the weak-link behaviour. Together with the SEM - EDS analysis, the shift of some of the XRD peaks, as well as the gradual decrease of with the dopant content x, suggests that the substitution is effective and some of the Sn is incorporated into the structure of the superconducting phases.
