Optical Magnetoelectric Effect in Multiferroic Materials: Evidence for a Lorentz Force Acting on a Ray of Light
Kei Sawada, Naoto Nagaosa
We theoretically propose that the optical analog of a Lorentz force acting on a ray of light is realized in multiferroic materials such as GaFeO showing the magnetoelectric eff…
Spin Hall effect of conserved current: Conditions for a nonzero spin Hall current
Naoyuki Sugimoto, Shigeki Onoda, Shuichi Murakami +1
We study the spin Hall effect taking into account the impurity scattering effect as general as possible with the focus on the definition of the spin current. The conserved bulk spi…
Gigantic Enhancement of Magneto-Chiral Effect in Photonic Crystals
Kei Sawada, Naoto Nagaosa
We theoretically propose a method to enhance dramatically a magneto-chiral(MC) effect by using the photonic crystals composed of a multiferroic material. The MC effect, the directi…
Spin current and magneto-electric effect in non-collinear magnets
Hosho Katsura, Naoto Nagaosa, Alexander V. Balatsky
A new microscopic mechanism of the magneto-electric (ME) effect based on the spin supercurrent is theoretically presented for non-collinear magnets. The close analogy between the s…
Anisotropic Electron-Phonon Coupling Uncovered By Angle-Resolved Photoemission
T. P. Devereaux, T. Cuk, Z. -X. Shen +1
Recently there has been an accumulation of experimental evidence in the high temperature superconductors suggesting the relevance of electron-phonon coupling in these materials. Th…
Entropy-Driven Reentrant Behavior in CMR Manganites
Nobuo Furukawa, Yukitoshi Motome, Naoto Nagaosa
We discuss the origin of the reentrant behaviors of insulating states above the Curie temperature of the colossal magnetoresistance manganites. We consider a system where charge or…
