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…
