The scaling behavior of the effective activation energy of high-quality epitaxial c-oriented Bi 2 Sr 2 Ca(Cu 1รx Co x ) 2 O d thin films with 0 6 x P 0.025 has been studied as a function of temperature and magnetic field. For all samples, the effective activation energy scales as U(T, l 0 H) = U 0 (
