The presence of the coupled spin and valley degrees of freedom makes silicene an important material for spintronics and valleytronics. Here we report a spin-valley filter effect in a silicene based antiferromagnetic/ferromagnetic junction.

Antiferromagnetic Spin Seebeck Effect [PDF]
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.

Magneto-Seebeck effect in magnetic tunnel junctions with perpendicular anisotropy
As one invigorated filed of spin caloritronics combining with spin, charge and heat current, the magneto-Seebeck effect has been experimentally and theoretically studied in spin tunneling thin films and nanostructures.

Wavelength-selective spin-current generator using infrared plasmonic metamaterials
A subwavelength plasmonic absorber is an ideal platform for absorbing light locally at a desired wavelength. Here, we demonstrate wavelength-selective spin current generation by combining plasmonic absorbers with Pt/yttrium-iron-garnet spintronic devices.

Spin-dependent Seebeck coefficients of Ni80Fe20 and Co in nanopillar spin valves [PDF]
We have experimentally determined the spin-dependent Seebeck coefficient of permalloy (Ni80Fe20) and cobalt (Co) using nanopillar spin valve devices, a stack of two ferromagnetic layers separated by a nonmagnetic layer.

Theory of magnon-driven spin Seebeck effect [PDF]
The spin Seebeck effect is a spin-motive force generated by a temperature gradient in a ferromagnet that can be detected via normal metal contacts through the inverse spin Hall effect [K. Uchida et al., Nature (London) 455, 778 (2008)].

Antiferromagnets (AFs) are prospective for next-generation high-density and high-speed spintronic applications due to their negligible stray field and ultrafast spin dynamics, notwithstanding the challenges in detecting and manipulating AF order with no ...

Spin mixing conductance enhancement by increasing magnetic density
We obtained the spin Seebeck effect enhancement in Y3Fe5O12 (YIG)/Pt system by inserting a very thin Ni80Fe20 at the interface of YIG/Pt. One of important parameters determining the spin Seebeck coefficient is the spin mixing conductance at the interface
