E. author Vicent López, José Luis author 2003-05 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. 0921-4526 10.1016/S0921-4526(02)02281-0 https://hdl.handle.net/20.500.14352/52088 http://dx.doi.org/10.1016/S0921-4526(02)02281-0 http://www.sciencedirect.com Vortex motion channeling effects in Nb with mesoscopic arrays of Ni lines
