Scanning Tunneling Microscope Operating as a Spin-diode
P. H. Penteado, F. M. Souza, A. C. Seridonio +2
We theoretically investigate spin-polarized transport in a system composed of a ferromagnetic Scanning Tunneling Microscope (STM) tip coupled to an adsorbed atom (adatom) on a host…
Enhanced photon-assisted spin transport in a quantum dot attached to ferromagnetic leads
Fabricio M. Souza, Thiago L. Carrara, E. Vernek
We investigate real-time dynamics of spin-polarized current in a quantum dot coupled to ferromagnetic leads in both parallel and antiparallel alignments. While an external bias vol…
Kondo screening regimes of a quantum dot with a single Mn ion
E. vernek, Fanyao Qu, F. M. Souza +2
We study the Kondo and transport properties of a quantum dot with a single magnetic Mn ion connected to metallic leads. By employing a numerical renormalization group technique we…
