Effect of magnons on interfacial phonon drag in YIG/metal systems
Arati Prakash, Jack Brangham, Sarah J. Watzman +2
We examine substrate-to-film interfacial phonon drag on typical spin Seebeck heterostructures, in particular studying the effect of ferromagnetic magnons on the phonon-electron dra…
Evidence for the role of the magnon energy relaxation length in the Spin Seebeck Effect
Arati Prakash, Benedetta Flebus, Jack Brangham +3
Temperature-dependent spin-Seebeck effect data on Pt|YIG (YFeO)|GGG (GdGaO) are reported for YIG films of various thicknesses. The effect is reported…
Dirac dispersion generates large Nernst effect in Weyl semimetals
Sarah J. Watzman, Timothy M. McCormick, Chandra Shekhar +6
Weyl semimetals expand research on topologically protected transport by adding bulk Berry monopoles with linearly dispersing electronic states and topologically robust, gapless sur…
Spin Seebeck effect through antiferromagnetic NiO
Arati Prakash, Jack Brangham, Fengyuan Yang +1
We report temperature-dependent spin-Seebeck measurements on Pt/YIG bilayers and Pt/NiO/YIG trilayers, where YIG (Yttrium iron garnet, YFeO) is an insulating ferrima…
Magnon-drag thermopower and Nernst coefficient in Fe, Co, and Ni
Sarah J. Watzman, Rembert A. Duine, Yaroslav Tserkovnyak +5
Magnon-drag is shown to dominate the thermopower of elemental Fe from 2 to 80 K and of elemental Co from 150 to 600 K; it is also shown to contribute to the thermopower of elementa…
