Mechanical, Electrical, and Magnetic Properties of Ni Nanocontacts
M. R. Calvo, M. J. Caturla, D. Jacob +2
The dynamic deformation upon stretching of Ni nanowires as those formed with mechanically controllable break junctions or with a scanning tunneling microscope is studied both exper…
The Kondo effect in ferromagnetic atomic contacts
M. R. Calvo, J. Fernández-Rossier, J. J. Palacios +3
Iron, cobalt and nickel are archetypal ferromagnetic metals. In bulk, electronic conduction in these materials takes place mainly through the and electrons, whereas the mag…
Formation of a Metallic Contact: Jump to Contact Revisited
C. Untiedt, M. J. Caturla, M. R. Calvo +3
The transition from tunneling to metallic contact between two surfaces does not always involve a jump, but can be smooth. We have observed that the configuration and material compo…
Formation of Atomic-Sized Contacts by Electrochemical Methods
M. R. Calvo, A. I. Mares, V. Climent +2
Electrochemical methods have recently become an interesting tool for fabricating and characterizing nanostructures at room temperature. Simplicity, low cost and reversibility are s…
Transport in magnetically ordered Pt nanocontacts
J. Fernández-Rossier, D. Jacob, C. Untiedt +1
Pt nanocontacts, like those formed in mechanically controlled break junctions, are shown to develop spontaneous local magnetic order. Our density functional calculations predict th…
High-bias stability of monatomic chains
R. H. M. Smit, C. Untiedt, J. M. van Ruitenbeek
For the metals Au, Pt and Ir it is possible to form freely suspended monatomic chains between bulk electrodes. The atomic chains sustain very large current densities, but finally f…
