Spin-Seebeck Effect: A Phonon Driven Spin Distribution

Physical Review Letters, 2011
Here we report on measurements of the spin-Seebeck effect in GaMnAs over an extended temperature range alongside the thermal conductivity, specific heat, magnetization, and thermoelectric power. The amplitude of the spin-Seebeck effect in GaMnAs scales with the thermal conductivity of the GaAs substrate and the phonon-drag contribution to the ...

Antiferromagnetic spin Seebeck effect across the spin-flop transition: A stochastic Ginzburg-Landau simulation [PDF]

, 2022
We investigate the antiferromagnetic spin Seebeck effect across the spin-flop transition in a numerical simulation based on the time-dependent Ginzburg-Landau equation for a bilayer of a uniaxial insulating antiferromagnet and an adjacent metal.

Multiple thermal spin transport performances of graphene nanoribbon heterojuction co-doped with Nitrogen and Boron

Scientific Reports, 2017
Graphene nanoribbon is a popular material in spintronics owing to its unique electronic properties. Here, we propose a novel spin caloritronics device based on zigzag graphene nanoribbon (ZGNR), which is a heterojunction consisting of a pure single ...

Strong Crystallographic Influence on Spin Hall Mechanism in PLD-Grown IrO₂ Thin Films

Nanomaterials, 2021
Spin-to-charge conversion is a central process in the emerging field of spintronics. One of its main applications is the electrical detection of spin currents, and for this, the inverse spin Hall effect (ISHE) has become one of the preferred methods.

Long-range spin Seebeck effect and acoustic spin pumping [PDF]

Nature Materials, 2011
Imagine that a metallic wire is attached to a part of a large insulator, which itself exhibits no magnetization. It seems impossible for electrons in the wire to register where the wire is positioned on the insulator. Here we found that, using a Ni₈₁Fe₁₉/Pt bilayer wire on an insulating sapphire plate, electrons in the wire recognize their position on ...

Magnetic anisotropies effect on the Spin-Seebeck response in spinel ferrite thin films

, 2022
: Observation of spin Seebeck effect (SSE) at room temperature in a weak ferromagnetic material, for example, a spinel zinc ferrite (ZnFe2O4) in bulk and thin film is demonstrated.

Unconventional scaling and significant enhancement of the spin Seebeck effect in multilayers [PDF]

, 2015
Spin Seebeck effects (SSEs) have been investigated in highly crystalline magnetic multilayer Fe3O4/Pt]n films. Voltage as well as power generated by the SSE were found to be significantly enhanced with increasing the number of layers n.

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

Advanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.

Valley–spin Seebeck effect in heavy group-IV monolayers

New Journal of Physics, 2017
Akin to electron spin, the valley has become another highly valued degree of freedom in modern electronics, specifically after tremendous studies on monolayers of group-IV materials, i.e. graphene, silicene, germanene and stanene.
