Journal ArticleDOI
All-electrical manipulation of magnetization dynamics in a ferromagnet by antiferromagnets with anisotropic spin Hall effects
Wei Zhang,Matthias B. Jungfleisch,Frank Freimuth,Wanjun Jiang,Joseph Sklenar,Joseph Sklenar,John E. Pearson,John B Ketterson,Yuriy Mokrousov,Axel Hoffmann +9 more
TL;DR: In this article, the spin-orbit torques of metallic CuAu-I-type antiferromagnets were investigated using spin-torque ferromagnetic resonance tuned by a dc-bias current.
Journal ArticleDOI
Flexible Polar Nanowires of Cs5BiP4Se12 from Weak Interactions between Coordination Complexes: Strong Nonlinear Optical Second Harmonic Generation
In Chung,In Chung,Jung Hwan Song,Joon I. Jang,Arthur J. Freeman,John B Ketterson,Mercouri G. Kanatzidis +6 more
TL;DR: Ab initio electronic structure calculations performed with the full-potential linearized augmented plane wave (FLAPW) method show that the band gap increases from its local density approximation (LDA) spin-orbit coupling value of 1.15 eV to the higher value of 2.0 eV when the screened-exchange LDA method is invoked and explain how the long nanowire nature of Cs(5)BiP(4)Se(12) emerges.
Journal ArticleDOI
Novel technique for dynamic surface tension and viscosity measurements at liquid-gas interfaces.
TL;DR: A novel means of generating and detecting surface waves at liquid-gas interfaces has been successfully developed using Electrocapillarity through specular reflection of a laser beam from the fluid surface to a position sensitive photodiode.
Journal ArticleDOI
Large optical nonlinearity of ITO nanorods for sub-picosecond all-optical modulation of the full-visible spectrum.
Peijun Guo,Richard D. Schaller,Leonidas E. Ocola,Benjamin T. Diroll,John B Ketterson,Robert P. H. Chang +5 more
TL;DR: This work reports on the sub-picosecond optical nonlinearity of indium tin oxide nanorod arrays (ITO-NRAs) following intraband, on-plasmon-resonance optical pumping, which enables modulation of the full-visible spectrum with large absolute change of transmission, favourable spectral tunability and beam-steering capability.
Journal ArticleDOI
Superconducting properties of V/Fe superlattices
TL;DR: In this paper, the superconducting properties of V/Fe superlatitices showing the interplay between ferromagnetism and superconductivity were investigated. But the results were limited to a few atomic planes.
