Formation of a magnetic hysteresis loop with respect to a bias voltage is investigated theoretically in a spin-valve device based on a single magnetic molecule. We consider a device consisting of two ferromagnetic electrodes bridged by a carbon nanotube, acting as a quantum dot, to which a spin-anisotropic molecule is exchange coupled. Such a coupling allows for transfer of angular momentum between the molecule and a spin current flowing through the dot, and thus, for switching orientation of… Expand

Time-dependent spintronic anisotropy in magnetic molecules
We theoretically study the quench dynamics of induced anisotropy of a large-spin magnetic molecule coupled to spin-polarized ferromagnetic leads. The real-time evolution is calculated by means of theExpand

Direct observation of quantum coherence in single-molecule magnets.
The clear observation of Rabi oscillations indicates that the authors can manipulate the spin coherently, an essential prerequisite for performing quantum computations. Expand
Controlling the state of quantum spins with electric currents
It is well known that a spin-polarized current can be used to manipulate the orientation of nanometre-scale magnets. This ability has now been extended to control the spin orientation of magneticExpand
