چکیده
In this paper we investigate the spin-resolved thermoelectric properties of strongly correlated molecular junctions in linear response regime. The magnetic molecule is modeled by a single orbital level to which core spin attached an exchange interaction. Using numerical renormalization group method analyze behavior (spin) Seebeck effect, heat conductance and figure merit for different model parameters molecule. We show that thermopower depends on strength type interaction as well molecule's anisotropy. When coupled ferromagnetic leads, reveal interplay between tunneling processes intrinsic Moreover, case finite accumulation system exhibits effect. demonstrate considerable effect can develop when easy-plane anisotropy, while sign magnitude

Antiferromagnetic Spin Seebeck Effect.
We report on the observation of the spin Seebeck effect in antiferromagnetic MnF_{2}. A device scale on-chip heater is deposited on a bilayer of MnF_{2} (110) (30 nm)/Pt (4 nm) grown by molecular beam epitaxy on a MgF_{2} (110) substrate. Using Pt as a spin detector layer, it is possible to measure the thermally generated spin current from MnF_{2} through the inverse spin Hall effect. The low ...
متن کاملMagnetic field control of the spin Seebeck effect
The origin of the suppression of the longitudinal spin Seebeck effect by applied magnetic fields is studied. We perform numerical simulations of the stochastic Landau-Lifshitz-Gilbert equation of motion for an atomistic spin model and calculate the magnon accumulation in linear temperature gradients for different strengths of applied magnetic fields and different length scales of the temperatur...
متن کاملLength Scale of the Spin Seebeck Effect.
We investigate the origin of the spin Seebeck effect in yttrium iron garnet (YIG) samples for film thicknesses from 20 nm to 50 μm at room temperature and 50 K. Our results reveal a characteristic increase of the longitudinal spin Seebeck effect amplitude with the thickness of the insulating ferrimagnetic YIG, which levels off at a critical thickness that increases with decreasing temperature....
متن کاملSpin Seebeck effect and thermoelectric phenomena in superconducting hybrids with magnetic textures or spin-orbit coupling
We theoretically consider the spin Seebeck effect, the charge Seebeck coefficient, and the thermoelectric figure of merit in superconducting hybrid structures including either magnetic textures or intrinsic spin-orbit coupling. We demonstrate that large magnitudes for all these quantities are obtainable in Josephson-based systems with either zero or a small externally applied magnetic field. Th...
متن کاملIntrinsic spin Seebeck effect in Au/YIG.
The acute magnetic proximity effects in Pt/YIG compromise the suitability of Pt as a spin current detector. We show that Au/YIG, with no anomalous Hall effect and a negligible magnetoresistance, allows the measurements of the intrinsic spin Seebeck effect with a magnitude much smaller than that in Pt/YIG. The experiment results are consistent with the spin polarized density functional calculati...
