Abstract

We have investigated the effect of pressure on the critical current density (Tc) at 77 K in YBa2Cu3O7-δ thin films with an ambient Jc varying from 104 to 4×106 A/cm2. The same linear enhancement of the relative Jc up to ≈24 percent at 16 kba r was observed for all samples. The observation can be explained in terms of the internal strain existing in the Y1:2:3 thin films.
