In particular, we study the effect of anisotropy for a Kagomé pinning network when longitudinal and transverse transport currents are applied. By solving the equations of motion for the vortex array numerically at zero temperature, we find different phases for the vortex dynamics, depending on the pinning and driving force. An unusual sequence of peaks for driving force along and perpendicular to the main lattice axes is observed for the differential resistance, reflecting the anisotropy of the transport properties and the complex behavior of the vortex system. This behavior may be understood in terms of interstitial pinning vacancies, which create channels of vortices with different pinning strengths. © 2012 Springer Science+Business Media, LLC.2277-2279engDifferential resistancePeriodic pinningSuperconductivityVortex dynamicsDifferential resistancesDynamical phasisPeriodic arraysPinning strengthTransport currentsZero temperaturesAnisotropyComplex networksEquations of motionTransport propertiesVortex flowRole of interstitial pinning in the dynamical phases of vortices in superconducting filmsArtigo10.1007/s10948-012-1532-2WOS:000323909500033Acesso restrito2-s2.0-8487828578282364329391369018628148275906320000-0002-5819-09570000-0002-3433-8574
