Spin-Transfer Torque on a Single Magnetic Adatom
Spin-Transfer Torque on a Single Magnetic Adatom
We theoretically show how the spin orientation of a single magnetic adatom can be controlled by spin polarized electrons in a scanning tunneling microscope configuration. The underlying physical mechanism is spin assisted inelastic tunneling. By changing the direction of the applied current, the orientation of the magnetic adatom can be …
