Highly c-axis oriented (Tl 0.5 ,Pb 0.5 )(Sr 0.8 ,Ba 0.2 ) 2 Ca 2 Cu 3 O y films with a thickness of 1.5 lm and 4 lm were prepared by screen printing method on untextured silver substrates. Tl-1223 films have the critical temperatures around 116 K with transition widths, DT, of 2 K, The microstructur
Y 0.8 Ca 0.2 Ba 2 Cu 3 O y samples with large range of oxygen content, have been systematically studied by means of positron annihilation technology, transport property measurements and X-ray diffraction. The positron lifetime parameters have a strong dependence on oxygen content y, and show evident
