Journal ArticleDOI
Magnetocapacitance effect in multiferroic BiMnO 3
TL;DR: In this article, the structural, magnetic, and electric properties of ferromagnetic perovskite structures were investigated and the changes in the dielectric constant were induced by the magnetic ordering.
Journal ArticleDOI
An Intrinsic Bond-Centered Electronic Glass with Unidirectional Domains in Underdoped Cuprates

TL;DR: In this paper, an atomic-resolution tunneling-asymmetry imaging was used to detect tunneling asymmetry in cuprates, and the emerging picture is then of a partial hole localization within an intrinsic electronic glass evolving, at higher hole densities, into complete delocalization and highest temperature superconductivity.
Journal ArticleDOI
Designed ferromagnetic, ferroelectric Bi(2)NiMnO(6).
TL;DR: A newly designed ferromagnetic, ferroelectric compound, Bi(2)NiMnO(6), was prepared by high-pressure synthesis at 6 GPa as mentioned in this paper.
Journal ArticleDOI
Superconductivity at 110 K in the infinite-layer compound (Sr1-xCax)1-yCuO2
TL;DR: In this article, the authors reported the isolation of an alkaline-earth-deficient infinite-layer phase, (Ca1-xSrx)1-yCuO2 (y~Ol), with Tc up to 110 K.
Journal ArticleDOI

TL;DR: It is reported that colossal negative thermal expansion (defined as linear expansion <−10−4 K−1 over a temperature range ~100 K) is accessible in perovskite oxides showing charge-transfer transitions.
