Journal ArticleDOI
Ferroelectricity from iron valence ordering in the charge-frustrated system LuFe2O4.
Naoshi Ikeda,Hiroyuki Ohsumi,Kenji Ohwada,Kenji Ishii,Toshiya Inami,Kazuhisa Kakurai,Youichi Murakami,Kenji Yoshii,Shigeo Mori,Yoichi Horibe,Hijiri Kito +10 more
TL;DR: Experimental evidence for ferroelectricity arising from electron correlations in the triangular mixed valence oxide, LuFe2O4 is reported, and resonant X-ray scattering measurements are used to determine the ordering of the Fe2+ and Fe3+ ions.
Journal ArticleDOI
Superconductivity in alkali-metal-doped picene
Ryoji Mitsuhashi,Yuta Suzuki,Yusuke Yamanari,Hiroki Mitamura,Takashi Kambe,Naoshi Ikeda,Hideki Okamoto,Hideki Okamoto,Akihiko Fujiwara,Minoru Yamaji,Naoko Kawasaki,Yutaka Maniwa,Yoshihiro Kubozono +12 more
TL;DR: It is reported that intercalating an alkali metal into picene, a wide-bandgap semiconducting solid hydrocarbon, produces metallic behaviour and superconductivity, and shows that organic hydrocarbons are promising candidates for improved Tc values.
Journal ArticleDOI
An organic thyristor
Fumiaki Sawano,Ichiro Terasaki,Hatsumi Mori,Takehiko Mori,Masashi Watanabe,Naoshi Ikeda,Yoshio Nogami,Yukio Noda +7 more
TL;DR: The discovery of a giant nonlinear resistance effect in the conducting organic salt θ-(BEDT-TTF)2CsCo(SCN)4, the voltage-current characteristics of which are essentially the same as those of a conventional thyristor, is reported.
Journal ArticleDOI
Magnetic and dielectric properties of RFe2O4, RFeMO4, and RGaCuO4 (R=Yb and Lu, M=Co and Cu)
TL;DR: In this article, the magnetic and dielectric properties of oxides were investigated for the isostructural oxides of $R{\mathrm{Fe}} and $R{Fe}M{O}O}, and they showed that magnetic ordering becomes short-ranged by the substitution at the Fe site.
Journal ArticleDOI
Magnetic structure of CoO studied by neutron and synchrotron x-ray diffraction
TL;DR: In this article, the authors performed neutron and synchrotron x-ray diffraction experiments on single crystals of CoO and found a series of magnetic reflections represented by a propagation vector along the tetragonal axis.
