The dissipative properties of (103)/(031) oriented films YBCO films grown on (110) SrTiO3 substrates were investigated in the vortex creep motion regime and compared with characteristics of c-axis oriented films deposited on both and (001)SrTiO3 and (001)NdGaO3 substrates. The current-voltage characteristics were measured at different temperatures, using a proper geometrical bridge configuration, able to test space anisotropy. The in-plane anisotropy due to the layered structure of the superconductor was clearly observed in the (103)/(031) oriented films. Experimental data are consistent with a thermal activated mechanism of vortex motion on a periodic pinning potential, attributed to intrinsic layer pinning. The intrinsic pinning energy per unit length of magnetic field line is evaluated as U0≈400 KeV/cm, in the low temperature limit. Consistently with theory, this energy is weakly dependent on temperature, the U/KBT ratio fading out at T ≈ Tc, where flux flow mechanism is activated for vortex motion.
