Tiivistelmä

The effect of BaZrO₃ (BZO) dopant concentration (0-9 wt-%) on magnetically obtained irreversibility field B_irr and upper critical field B_c₂ is investigated in YBa₂Cu₃O_6+x (YBCO) thin films prepared by pulsed laser deposition on SrTiO₃ (001) (STO) substrates. It is found that the magnetic determination of B_irr and B_c2 works well. The results show that BZO-doping increases B_c2 in all concentrations, implying a change in the coherence length and band structure of the superconductor.
