Modulating the Spin Seebeck Effect in Co₂FeAl Heusler Alloy for Sensor Applications [PDF]

Sensors, 2020
The thermoelectric conversion technique has been explored in a broad range of heat-flow sensors. In this context, the Spin Seebeck Effect emerges as an attractive candidate for biosensor applications, not only for the sensibility improvement but also for

Spin Seebeck effect mediated reversal of vortex-Nernst effect in superconductor-ferromagnet bilayers [PDF]

Scientific Reports, 2023
We report on the observation of sign reversal of vortex-Nernst effect in epitaxial NbN/Fe bilayers deposited on MgO (001) substrates. Strong coupling between vortex magnetisation and ferromagnetic magnetisation at the NbN/Fe bilayer interface is ...

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 ...

Spin Hall magnetoresistance and spin Seebeck effect in Pt |CoCr2O4 heterostructures [PDF]

Science and Technology of Advanced Materials
This study delves into spin current-induced phenomena, such as spin-Hall magnetoresistance and the spin Seebeck effect within Pt films deposited on a noncollinear magnet, CoCr[Formula: see text]O[Formula: see text] (CCO), particularly at low temperatures.

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.

Metal-free magnetism, spin-dependent Seebeck effect, and spin-Seebeck diode effect in armchair graphene nanoribbons [PDF]

Scientific Reports, 2018
AbstractMetal-free magnetism and spin caloritronics are at the forefront of condensed-matter physics. Here, the electronic structures and thermal spin-dependent transport properties of armchair graphene nanoribbons (N-AGNRs), where N is the ribbon width (N = 5–23), are systematically studied.

Thermal spin transport phenomena and their correlation to magnetic properties of metallic Pt/Co1-xFex and Pt/Ni1-xFex bilayers [PDF]

Science and Technology of Advanced Materials
We investigate the thermal spin transport phenomena in ferromagnetic metals with an adjacent spin-polarized Pt layer examining sputter-deposited Pt/Co1-xFex and Pt/Ni1-xFex bilayers.

Room temperature and low-field resonant enhancement of spin Seebeck effect in partially compensated magnets [PDF]

Nature Communications, 2019
The spin Seebeck effect (SSE) converts thermally induced magnetization dynamics in magnetic materials to spin currents, but is so far an inefficient process.

Spin Seebeck in the weakly exchange-coupled Van der Waals antiferromagnet across the spin-flip transition

Nature Communications
Spin Seebeck effect refers to the creation of spin currents due to a temperature gradient in the magnetic materials or across magnet-normal metal interfaces, which can be electrically detected through the inverse spin Hall effect when in contact with ...

Spin Seebeck Imaging of Spin-Torque Switching in Antiferromagnetic Pt/NiO Heterostructures

Physical Review X, 2019
As electrical control of Néel order opens the door to reliable antiferromagnetic spintronic devices, understanding the microscopic mechanisms of antiferromagnetic switching is crucial.
