Journal ArticleDOI
Ferromagnetic resonance spectra of permalloy nano-ellipses as building blocks for complex magnonic lattices
Wonbae Bang,Wonbae Bang,Federico Montoncello,Mojtaba Taghipour Kaffash,Axel Hoffmann,John B Ketterson,Matthias B. Jungfleisch +6 more
TL;DR: In this article, the angular dependent magnetic field and microwave frequency response of isolated mesoscopic permalloy nanoellipses for geometries in which the static magnetic field is either parallel or perpendicular to the microwave magnetic field were characterized.
Journal ArticleDOI
Phonon-pump electronic-probe study of methylammonium lead iodide reveals electronically decoupled organic and inorganic sublattices

TL;DR: In this article, transient absorption measurements employing an infrared pump pulse tuned to a methylammonium vibration were used to determine whether the large dipole moment of the organic cation and dynamic disorder benefit the optoelectronic properties of CH3NH3PbI3.
Journal ArticleDOI
Determination of the viscosity of valinomycin monolayers as a function of surface density and a comment on conformation
TL;DR: Determination de la viscosite surperficielle de la valinomycine etalee sur des supports aqueux tamponnes a pH 6,7±0,1 avec du triphosphate as discussed by the authors.
Journal ArticleDOI

Large magnetoresistance in post-annealed polycrystalline and epitaxial Bi thin films
Sunglae Cho,Yunki Kim,Linda J. Olafsen,Igor Vurgaftman,Arthur J Freeman,George K. Wong,George K. Wong,Jerry R. Meyer,Craig A. Hoffman,John B Ketterson +9 more
TL;DR: In this article, a large increase in the magnetoresistance of polycrystalline and epitaxial thin Bi films, which were subjected to a post-annealing procedure at 3°C below the Bi melting point, was observed.
