Abstract
In this paper we present a quantitative magneto-optical analysis on c-axis oriented YBCO thin films, as grown and irradiated with 3.5 MeV protons at three different fluences. Magneto-optical measurements were performed over the temperature range 5–70 K and at magnetic fields up to 150 mT. The local current density values were obtained from the field maps by means of the Biot-Savart law inversion. The critical current density (Jc) is locally defined as the current density where the maximum pinning efficiency is reached. This procedure allows obtaining Jc independently of dissipation threshold criteria or critical state model. A Jc enhancement emerges for irradiation at the lowest fluence ( Ф +2.5⋅1015 cm−2) in the whole investigate temperature range. On the contrary at increasing the irradiation dose a temperature-dependent crossover from an enhancement to a worsening of Jc is exhibited.
