Journal ArticleDOI
Experimental Test of the Spin Mixing Interface Conductivity Concept
Mathias Weiler,Matthias Althammer,Michael Schreier,Johannes Lotze,Matthias Pernpeintner,Sibylle Meyer,Hans Huebl,Rudolf Gross,Akashdeep Kamra,Jiang Xiao,Yan Ting Chen,Hujun Jiao,Gerrit E. W. Bauer,Gerrit E. W. Bauer,Sebastian T. B. Goennenwein +14 more
TL;DR: The experimental results fully support present, exclusively spin current-based, theoretical models using a single set of plausible parameters for spin mixing conductance, spin Hall angle, and spin diffusion length.
Journal ArticleDOI
Magnon, phonon, and electron temperature profiles and the spin Seebeck effect in magnetic insulator/normal metal hybrid structures
Michael Schreier,Akashdeep Kamra,Mathias Weiler,Jiang Xiao,Gerrit E. W. Bauer,Gerrit E. W. Bauer,Rudolf Gross,Sebastian T. B. Goennenwein +7 more
TL;DR: In this paper, the phonon, electron, and magnon temperature profiles in yttrium iron garnet/platinum bilayers were calculated by diffusive theory with appropriate boundary conditions, in particular taking into account interfacial thermal resistances.
Journal ArticleDOI
Origin of the spin Seebeck effect in compensated ferrimagnets
Stephan Geprägs,Andreas Kehlberger,Francesco Della Coletta,Zhiyong Qiu,Er-Jia Guo,T. Schulz,Christian Mix,Sibylle Meyer,Akashdeep Kamra,Akashdeep Kamra,Matthias Althammer,Hans Huebl,Gerhard Jakob,Yuichi Ohnuma,Yuichi Ohnuma,Hiroto Adachi,Joseph Barker,Sadamichi Maekawa,Gerrit E. W. Bauer,Gerrit E. W. Bauer,Eiji Saitoh,Rudolf Gross,Rudolf Gross,Sebastian T. B. Goennenwein,Mathias Kläui +24 more
TL;DR: It is demonstrated that higher-energy exchange magnons play a key role in the SSE, which is caused by thermally excited spin dynamics that are converted to a voltage by the inverse spin Hall effect at the interface to a heavy metal contact.
Journal ArticleDOI
Coherent elastic excitation of spin waves
TL;DR: In this article, the authors model the injection of elastic waves into a ferromagnetic film (F) by a nonmagnetic transducer (N) and compare the configurations in which the magnetization is normal and parallel to the wave propagation.
Journal ArticleDOI
Super-Poissonian Shot Noise of Squeezed-Magnon Mediated Spin Transport.
Akashdeep Kamra,Wolfgang Belzig +1 more
TL;DR: It is found that the shot noise of the spin current traversing the F|N interface when F is subjected to a coherent microwave drive is frequency independent up to the drive frequency, and increases linearly with frequency thereafter.
