We address electron spin resonance of single magnetic moments in a tunnel junction using time-dependent electric fields and spin-polarized current. We show that the tunneling current directly depends on the local magnetic moment and that the frequency of the external electric field mixes with the characteristic Larmor frequency of the local spin. The importance of the spin-polarized current induced anisotropy fields acting on the local spin moment is, moreover, demonstrated. Our proposed model…

Nature of tunneling electron spin resonance of an isolated surface spin
A phenomenological model has been proposed for tunneling electron spin resonance (ESR) of an isolated surface spin situated in a scanning tunneling microscope (STM), which explains the dependence of
Spin transfer torque induced paramagnetic resonance
We show how the spin-transfer torque generated by an AC voltage may be used to excite a paramagnetic resonance of an atomic spin deposited on a metallic surface. This mechanism is independent of the
Tuning Single-Atom Electron Spin Resonance in a Vector-Magnetic Field.
It is shown how the ESR amplitude can be greatly improved by optimizing the magnetic fields, and how the stray field from the magnetic STM tip is a versatile tool, which promises to make this technique available in many existing STM systems.
Single spin resonance driven by electric modulation of the g -factor anisotropy
We address the problem of electronic and nuclear spin resonance of an individual atom on a surface driven by a scanning tunnelling microscope. Several mechanisms have been proposed so far, some of

Recent experimental conductance measurements performed on paramagnetic molecular adsorbates on a superconducting surface, using superconducting scanning tunneling microscopy techniques, are
Tunneling measurement of a single quantum spin.
This work proposes an experiment to observe the Zeno effect in a tunneling system and describes how the tunneling current may be used to read a qubit represented by a single spin 1/2.
Dynamical spin-electric coupling in a quantum dot
Due to the spin-orbital coupling in an anisotropic semiconductor quantum dot, a freely precessing electron spin produces a time-dependent charge density. This creates a sizable electric field outside
STM NMR and nuclear spin noise
Fluctuations of an electronic spin can be revealed in the tunneling current fluctuations of a scanning tunneling microscope (STM). We consider fluctuations of the electronic spin due to coupling to
Quantum electronic transport through a precessing spin.
The conductance through a local nuclear spin precessing in a magnetic field is studied by using the equations-of-motion approach and it is found that the spin-flip coupling between the electrons on the spin site and the leads produces the conductance oscillation.
Electronic spin detection in molecules using scanning-tunneling- microscopy-assisted electron-spin resonance
By combining the spatial resolution of a scanning-tunneling microscope (STM) with the electronic spin sensitivity of electron-spin resonance, we show that it is possible to detect the presence of

The dynamics of a single spin embedded in the tunnel junction (quantum point contact) between ferromagnets is addressed. Using the Keldysh technique, we derive a quantum Langevin equation. As a

The theory shows that the incoming electron spin strongly couples with that of the adsorbate so that memory of the initial spin state is lost, leading to large excitation efficiencies.
Spin inelastic electron tunneling spectroscopy on local spin adsorbed on surface.
It is argued that the observed conductance signatures are caused by transitions between the spin states that have opened due to exchange coupling between the local spins and the tunneling electrons, and are directly interpretable in terms of inelastic transitions energies.
