Crespo del Arco, Patricia ; Multigner, M. ; Castaño, F. J. ; Casero, R. ; Hernando Grande, Antonio | American Physical Society | 2000-06-01In this paper, the production of FeCu-based FeCuZr amorphous alloys by ball milling is reported. The thermal dependence of magnetization for the [Fe_(0.5)Cu_(0.5)]_85Zr_(15) (at. %) amorphous alloy has been found to show a dramatic field depende[...]texto impreso

A. ; Schuller, Ivan K. ; Vicent López, José Luis | American Institute of Physics | 2011-10-31Strong superconducting pinning effects are observed from magnetic landscapes produced by arrays of circular rings with varying magnetic remanent states. The collective and the background pinning of superconducting Nb films is strongly enhanced b[...]texto impreso

A. ; Schuller, Ivan K. ; Vicent López, José Luis | American Physical Society | 2009-12A ratchet effect (the rectification of an ac injected current) which is purely magnetic in origin has been observed in a superconducting-magnetic nanostructure hybrid. The hybrid consists of a superconducting Nb film in contact with an array of [...]texto impreso
Hernando Grande, Antonio ; Crespo del Arco, Patricia ; Castaño, F. J. ; Arcas, J. ; Multigner, M. ; Barandiaran, J. M. ; Fernández Barquín, L. | American Physical Society | 2000-01-01We report the existence of a thermally induced sharp increase of thermoremanence around the Curie temperature of Invar-like Fe-Zr(B,Cu) soft magnetic glasses. Neutron-diffraction measurements indicate that a true enhancement of the average local[...]
