González thanks Spanish Ministerio de Ciencia y Tecnología for a Ramón y Cajal contract.Ordered arrays of submicrometric Ni lines have been fabricated in sputtered Nb films. Magnetotransport R(H) and (I, V) curves were measured close to the critical temperature using a cross-shape bridge that allows us to apply current in two directions: parallel or perpendicular to the lines. The experimental results show anisotropic vortex motion with clear channeling effects. In R(H) data, magnetic features appear but they are absent in the (I, V) curves.engjournal articlehttp://dx.doi.org/10.1016/S0921-4526(02)02281-0http://www.sciencedirect.comopen access538.9SuperconductivityVorticesNanostructuresFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
