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…
Picosecond spin Seebeck effect
Johannes Kimling, Gyung-Min Choi, Jack T. Brangham +5
We report time-resolved magneto-optic Kerr effect measurements of the longitudinal spin Seebeck effect driven by an interfacial temperature difference between itinerant electrons a…
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…
Arachne - A web-based event viewer for MINERvA
N. Tagg, J. Brangham, J. Chvojka +35
Neutrino interaction events in the MINERvA detector are visually represented with a web-based tool called Arachne. Data are retrieved from a central server via AJAX, and client-sid…
