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…
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…
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…
Imaging Magnetization Structure and Dynamics in Ultrathin YIG/Pt Bilayers with High Sensitivity Using the Time-Resolved Longitudinal Spin Seebeck Effect
Jason M. Bartell, Colin L. Jermain, Sriharsha V. Aradhya +4
We demonstrate an instrument for time-resolved magnetic imaging that is highly sensitive to the in-plane magnetization state and dynamics of thin-film bilayers of yttrium iron garn…
Increased low-temperature damping in yttrium iron garnet thin films
C. L. Jermain, S. V. Aradhya, J. T. Brangham +6
We report measurements of the frequency and temperature dependence of ferromagnetic resonance (FMR) for a 15-nm-thick yttrium iron garnet (YIG) film grown by off-axis sputtering. A…
Strong modulation of spin currents in bilayer graphene by static and fluctuating proximity exchange fields
Simranjeet Singh, Jyoti Katoch, Tiancong Zhu +6
Two dimensional (2D) materials provide a unique platform to explore the full potential of magnetic proximity driven phenomena, which can be further used for applications in next ge…
