Measurements of anisotropic transport properties (dc and high-frequency regime) of driven vortex matter in YBa2Cu3O7-xwith elongated strong-pinning sites (c-axis aligned, self-assembled BaZrO3nanorods) are used to demonstrate that the effective-mass angular scaling takes place only in intrinsic physical quantities (flux-flow resistivity), and not in pinning-related Labusch parameter and critical currents. Comparison of the dynamics at different time scales shows evidence for a transition of the vortex matter toward a Mott phase, driven by the presence of nanorods. The strong pinning in dc arises partially from a dynamic effect. © 2013 Author(s).
