Mechanical, Electrical, and Magnetic Properties of Ni Nanocontacts

By M. R. Calvo, M. J. Caturla, D. Jacob, C. Untiedt and J. J. Palacios


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 experimentally and theoretically. Molecular dynamics simulations of the breaking process are performed. In addition, and in order to compare with experiments, we also compute the transport properties in the last stages before failure using the first-principles implementation of Landauer's formalism included in our transport package ALACANT.Comment: 5 pages, 6 figure
