Vortex motion channeling effects in Nb with mesoscopic arrays of Ni lines González Herrera, Elvira María Anguita, J. V. Villegas, J. E. Vicent López, José Luis 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. 2023-06-20T12:39:27Z 2023-06-20T12:39:27Z 2023-06-20T12:39:27Z 2003-05 journal article https://hdl.handle.net/20.500.14352/52088 0921-4526 10.1016/S0921-4526(02)02281-0 eng MAT99-0724 open access Elsevier Science BV
