Thermoelectric performance of spin Seebeck effect in Fe3O4/Pt-based thin film heterostructures [PDF]
APL Materials, 2016 We report a systematic study on the thermoelectric performance of spin Seebeck devices based on Fe3O4/Pt junction systems. We explore two types of device geometries: a spin Hall thermopile and spin Seebeck multilayer structures.

Intrinsic nonlinear Nernst and Seebeck effect [PDF]
New Journal of PhysicsThe Nernst and Seebeck effects are crucial for thermoelectric energy harvesting. However, the linear anomalous Nernst effect requires magnetic materials with intrinsically broken time-reversal symmetry.

Length Scale of the Spin Seebeck Effect [PDF]
Physical Review Letters, 2015 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 ...

Theory of the spin Seebeck effect [PDF]
Reports on Progress in Physics, 2013 The spin Seebeck effect refers to the generation of a spin voltage caused by a temperature gradient in a ferromagnet, which enables the thermal injection of spin currents from the ferromagnet into an attached nonmagnetic metal over a macroscopic scale of several millimeters.

Charged Colloids at the Metal–Electrolyte Interface
Colloids and Interfaces, 2022 We discuss the peculiarities of the structure of the interface between a metal and a stable colloidal dispersion of charged nanoparticles in an electrolyte. It is demonstrated that a quasi-2D ionic structure of elevated density arises in its vicinity due

Seebeck Effect of Dirac Electrons
Journal of the Physical Society of Japan, 2022 We study the Seebeck effect in the three-dimensional Dirac electron system based on the linear response theory with Luttinger's gravitational potential. The Seebeck coefficient $S$ is defined by $S = L_{12} / L_{11} T$, where $T$ is the temperature, and $L_{11}$ and $L_{12}$ are the longitudinal response coefficients of the charge current to the ...
