Abstract

Effect of Sr substitution on irreversible properties and lattice dynamics of Hg,Pb-1223 phases was studied. We found that flux pinning properties in high magnetic fields essentially improved by substitutions of Hg by Pb and Ba by Sr. Consideration of lattice dynamics figured out the role of lead and strontium on phase stability and hole doping of CuO₂ layers. Investigation of phase composition and micro structural features of the samples allowed us to suggest a possible mechanism of Hg,Pb-1223 phase formation. The substituted samples possessed an improved chemical stability and allowed their further utilization for materials preparation. As an example, nearly single phase thick film on MgO substrate with the T_c of 120 K was obtained by screen printing method. Despite of the very high intragrain critical current density (j_c = 3 × 10⁵ A/cm², H = 0, 77 K), transport j_c was restricted by formation of 'weak links' on the grain boundaries.
