Long lifetime of thermally-excited magnons in bulk yttrium iron garnet
John S. Jamison, Zihao Yang, Brandon L. Giles +5
Spin currents are generated within the bulk of magnetic materials due to heat flow, an effect called intrinsic spin-Seebeck. This bulk bosonic spin current consists of a diffusing…
Thermally Driven Long Range Magnon Spin Currents in Yttrium Iron Garnet due to Intrinsic Spin Seebeck Effect
Brandon L. Giles, Zihao Yang, John S. Jamison +5
The longitudinal spin Seebeck effect refers to the generation of a spin current when heat flows across a normal metal/magnetic insulator interface. Until recently, most explanation…
Scalable Nernst Thermoelectric Power using a Coiled Galfenol Wire
Zihao Yang, Emilio A. Codecido, Jason Marquez +3
The Nernst thermopower usually is considered far too weak in most metals for waste heat recovery. However, its transverse orientation gives it an advantage over the Seebeck effect…
The effect of the magnon dispersion on the longitudinal spin Seebeck effect in yttrium iron garnets (YIG)
Hyungyu Jin, Stephen R. Boona, Zihao Yang +2
We study the temperature dependence of the longitudinal spin-Seebeck effect (LSSE) in a yttrium iron garnet Y3Fe5O12 (YIG) / Pt system for samples of different thicknesses. In this…
Long range pure magnon spin diffusion observed in a non-local spin-Seebeck geometry
Brandon L. Giles, Zihao Yang, John Jamison +1
The spin diffusion length for thermally excited magnon spins is measured by utilizing a non-local spin-Seebeck effect measurement. In a bulk single crystal of yttrium iron garnet (…
Anisotropic defect-induced ferromagnetism and transport in Gd-doped GaN two-dimensional electron gasses
Zihao Yang, Thomas F. Kent, Jing Yang +3
Here we report on the effect of rare earth Gd-doping on the magnetic properties and magnetotransport of GaN two-dimensional electron gasses (2DEGs). Samples are grown by plasma-ass…
