We measured the critical current density Jc 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 Jc of the films obtained by PLD usually overcomes the Jc values of the sputtered films in the whole investigated (H, T) domain.
