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…
Magnetic and orbital blocking in Ni nanocontacts
David Jacob, J. Fernández-Rossier, J. J. Palacios
We address the fundamental question of whether magneto-resistance (MR) of atomic-sized contacts of Nickel is very large because of the formation of a domain wall (DW) at the neck.…
Charge-localization and isospin-blockade in vertical double quantum dots
David Jacob, Bernhard Wunsch, Daniela Pfannkuche
Charge localization seems unlikely to occur in two vertically coupled symmetric quantum dots even if a small bias voltage breaks the exact isospin-symmetry of the system. However f…
