RT Journal Article T1 Vortex motion channeling effects in Nb with mesoscopic arrays of Ni lines A1 González Herrera, Elvira María A1 Anguita, J. V. A1 Villegas, J. E. A1 Vicent López, José Luis AB 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.
