Abstract

We have investigated magnetic flux relaxation at low temperatures in a 90 nm epitaxial coevaporated film on YBa₂Cu₃O_7-δ superconductor. This film is characterized by a high critical current J_c of 3.5 × 10¹¹ A m^-2 at 4.2 K, and 1.3 × 10¹⁰ A m^-2 at 77 K. Although J_c depends strongly on the applied magnetic field B the magnetic relaxation is only weakly dependent on B. Also the magnetic relaxation does not vanish at zero temperature, indicating that besides a thermally activated process there is another intrinsic process working.
