Journal ArticleDOI
Length Scale of the Spin Seebeck Effect.
Andreas Kehlberger,Ulrike Ritzmann,Denise Hinzke,Er-Jia Guo,Joel Cramer,Gerhard Jakob,Mehmet C. Onbasli,Dong-Hun Kim,Caroline A. Ross,Matthias B. Jungfleisch,Matthias B. Jungfleisch,Burkard Hillebrands,Ulrich Nowak,Mathias Kläui +13 more
TL;DR: Comparison to numerical simulations of thermal magnonic spin currents yields qualitative agreement for the thickness dependence resulting from the finite magnon propagation length and at low temperature, even quantitative agreement with the simulations is found.
Journal ArticleDOI
Ultrahigh energy storage in superparaelectric relaxor ferroelectrics
Hao Pan,Shun Lan,Shiqi Xu,Qinghua Zhang,Hongbao Yao,Yi-Qian Liu,Fanqi Meng,Er-Jia Guo,Lin Gu,Di Yi,Xiao Renshaw Wang,Houbing Huang,Judith L. MacManus-Driscoll,Long Qing Chen,Kui Juan Jin,Ce-Wen Nan,Yuanhua Lin +16 more
TL;DR: In this paper, relaxor ferroelectrics characterized by nanodomains are used for energy storage in advanced electronics and high power electrical systems, and they are shown to be fundamental to advanced electronics.
Journal ArticleDOI

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
Emerging magnetism and anomalous Hall effect in iridate-manganite heterostructures.
John Nichols,Xiang Gao,Shinbuhm Lee,Tricia L. Meyer,John W. Freeland,Valeria Lauter,Di Yi,Jian Liu,Daniel Haskel,Jonathan R. Petrie,Er-Jia Guo,Andreas Herklotz,Dongkyu Lee,Thomas Z. Ward,Gyula Eres,Michael R. Fitzsimmons,Ho Nyung Lee +16 more
TL;DR: It is observed that the interfacial coupling between the 3d antiferromagnetic insulator SrMnO3 and the 5d paramagnetic metal SrIrO3 is enormously strong, yielding an anomalous Hall response as the result of charge transfer driven interfacial ferromagnetism.
Journal ArticleDOI
Influence of Thickness and Interface on the Low-Temperature Enhancement of the Spin Seebeck Effect in YIG Films
Er-Jia Guo,Er-Jia Guo,Joel Cramer,Andreas Kehlberger,Ciaran Ferguson,Donald A. MacLaren,Gerhard Jakob,Mathias Kläui +7 more
TL;DR: In this article, the spin Seebeck effect depends on temperature and material properties, and the spin seebeck effect is observed in metal, semiconductors, and insulators, in which a temperature gradient results in current flow.
