Opis:: Synthesis of Pb, Fe and Cd doped Hg-based $HgBa_{2}Ca_{2}Cu_{3}O_{8 + δ}$ (Hg-1223) superconducting ceramics was performed. Hg-free precursor $Ba_{2}Ca_{2}Cu_{3}O_{8 + δ}$ with high chemical homogeneity and reactivity obtained by the sol-gel method was used. The superconducting and impurity phases were determined by means of scanning electron microscopy and microprobe analysis. The results of resistivity and magnetization measurements for different kinds of doped elements were presented.

Opis:: Complex investigations of the photoinduced changes in YBa$\text{}_{2}$Cu$\text{}_{3}$O$\text{}_{x}$ single crystals were performed. As laser sources the low-power He-Ne, He-Cd, He-Se, N$\text{}_{2}$ lasers and YAG:Nd, XeCl pulsed lasers were used. For the investigations the crystalline samples both in super- and semiconducting phases were chosen. A considerably strong dependence of a defectiveness parameter x on the laser power, wavelength and external conditions was observed. The oxygen parameter x shows a tendency to increase for the initially semiconducting phase and to decrease for superconductors. The most interesting result were obtained using XeCl excimer laser, where corresponding changes were observed only under applied hydrostatic pressure (up to 200 MPa) in oxygen atmosphere. In all the cases the penetration depth of the new induced superconducting phase was within 5.5-6.5 μm.
