It is shown that the magnetization curves P(m)(B, T) of epitaxial YBa2Cu3Ox films in the wide temperature range of 20-80 K may be described by the universal scaling relation. The temperature and field dependences of the critical current density are studied. The field dependences for thermally activated magnetic flux creep are investigated. The activation energy of Abrikosov vortices, being 0,25 eV at 8 = 70 K, is found.
