TL;DR: In this article, it was shown that the magnetoresistive response increases dramatically when the Curie temperature (T C) is reduced, and that the massive magnetoresistance in low-T C systems can be explained by percolative transport through the ferromagnetic domains; this depends sensitively on the relative spin orientation of adjacent magnetoric domains which can be controlled by applied magnetic fields.
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
Pairing of charge-ordered stripes in (La,Ca)MnO 3
TL;DR: In this article, a different pattern of charge localization in the charge-ordered phase of the manganese oxide La1−xCaxMnO3 (x ⩾ 0.5) was reported.
Journal ArticleDOI

TL;DR: Using Lorenz microscopy and small-angle electron diffraction, it is directly present that the chiral magnetic soliton lattice continuously evolves from a chiral helimagnetic structure in small magnetic fields in Cr(1/3)NbS2.

TL;DR: It is reported that the Fe4+-based quadruple perovskite CaCu3Fe4O12 has high activity, which is comparable to or exceeding those of state-of-the-art catalysts such as Ba 0.5Sr0.5Co0.8Fe0.2O3−δ and the gold standard RuO2.
