Improper ferroelectricity in perovskite oxide artificial superlattices

TL;DR: It is shown that superlattices with very short periods possess a new form of interface coupling, based on rotational distortions, which gives rise to ‘improper’ ferroelectricity, and an approach is suggested,based on interface engineering, to produce artificial materials with unique properties.
Journal ArticleDOI

Improper ferroelectricity in perovskite oxide artificial superlattices

TL;DR: In this article, the rotational distortions of the oxygen atoms are exploited to give rise to improper ferroelectricity in superlattices with very short periods, where the ground state of the system is not purely Ferroelectric, but also primarily involves antiferrodistortive rotations.
Journal ArticleDOI

Raman and infrared spectra of multiferroic bismuth ferrite from first principles

TL;DR: In this article, the entire zone-center phonon spectrum of the $R3c$ ferroelectric antiferromagnetic phase of bismuth ferrite was computed using a first-principles approach based on density functional theory.
Journal ArticleDOI

New Insight into the Vibrational Behavior of Nickel Hydroxide and Oxyhydroxide Using Inelastic Neutron Scattering, Far/Mid-Infrared and Raman Spectroscopies

TL;DR: In this article, the electrochemical properties of β-type nickel (oxy)hydroxides Ni(OH)2 and NiO(OH), and their structural features are investigated.
