Abstract

We measured the critical current density J_c of optimally doped YBa₂Cu₃O₇-_δ thin films obtained by dc sputtering on (100) oriented SrTiO₃ substrates and by pulsed laser deposition (PLD) on (100) oriented MgO substrates with SrTiO₃ buffers. Jc at various temperatures T was determined from the magnetization curves registered with a vibrating sample magnetometer for an external magnetic field H (oriented along the c axis) up to 90 kOe. It was found that J_c of the films obtained by PLD usually overcomes the J_c values of the sputtered films in the whole investigated (H, T) domain.
