Restoration of ferroelectricity by pressure in multiferroic

Journal of Magnetism and Magnetic Materials, 2007
Abstract The multiferroic properties of HoMn 2 O 5 have been extensively studied to gain understanding of the magneto-dielectric coupling in this compound. In this work, dielectric measurements as well as polarization measurements in isotropic pressure up to 18 kbar are presented.

Ferroelastic-ferroelectric multiferroics in a bilayer lattice

Physical Review B, 2021
Two-dimensional multiferroics, combined with ferroelastic and ferroelectric orders, enable unprecedented exploration of applications, such as high-density multistate storage. However, current ferroelastic-ferroelectric-multiferroic research is based on the paradigm of unique symmetry in a single-layer lattice, which restricts ferroelastic ...

Multiferroic Dislocations in Ferroelectric PbTiO₃

Nano Letters, 2017
Ultrathin multiferroics with coupled ferroelectric and ferromagnetic order parameters hold promise for novel technological paradigms, such as extremely thin magnetoelectric memories. However, these ferroic orders and their functions inevitably disappear below a fundamental size limit of several nanometers. Herein, we propose a novel design strategy for

Ferroelectrics And Multiferroics For Next Generation Photovoltaics [PDF]

Advanced Materials Letters, 2015
Growing energy crisis and environmental issues demand alternative source of green energy. In recent years ferroelectrics and multiferroics have got renewed attention for the breakthrough in photovoltaic application. Multiferroic is an appealing class of material, having two or more ferroic properties intimately coupled to each other.

Orbital order, magnetism, and ferroelectricity of multiferroic

Journal of Magnetism and Magnetic Materials, 2007
Abstract Epitaxial thin films of multiferroic BiMnO 3 were synthesized on SrTiO 3 substrates. Long range ordering of the Mn 3 + e g orbitals was probed with Mn K -edge resonant X-ray scattering. Magnetic properties of the thin films were also investigated.

Towards ferroelectric and multiferroic nanostructures and their characterisation

International Journal of Nanotechnology, 2008
We summarise here our efforts toward the fabrication and characterisation of ferroelectric and multiferroic films and structures. First, we discuss the challenges related with the fabrication and characterisation of nanostructures of functional complex oxides. In particular, to demonstrate the functionality of our films and especially of our structures,

Multiferroic and Ferroelectric Rashba Semiconductors

2018
The coupling of different phenomena, such as ferroelectric or magnetic order, often mediated by spin-orbit interaction, offers a rich playground for emergent phenomena in multifunctional materials. In this chapter, we focus on multiferroics and ferroelectric semiconductors showing a strong Rashba effect, we explain the motivations behind their study ...

Ferroelectrics, magnetoelectrics, and multiferroics

2014
As discussed at the beginning of Chapter 7, there can exist different types of ordering phenomena connected with charge degrees of freedom. Examples are ordering of charges themselves (charge “monopoles”); ordering of electric dipoles, giving ferroelectricity (FE); or ordering of electric quadrupoles, which happens in orbital ordering.

Tuning the Ferroelectric Polarization in a Multiferroic Metal–Organic Framework

Journal of the American Chemical Society, 2013
We perform density functional theory calculations on a recently synthesized metal-organic framework (MOF) with a perovskite-like topology ABX3, i.e., [CH3CH2NH3]Mn(HCOO)3, and predict a multiferroic behavior, i.e., a coexistence of ferroelectricity and ferromagnetism.

Characteristics and controllability of vortices in ferromagnetics, ferroelectrics, and multiferroics

Reports on Progress in Physics, 2017
Topological defects in condensed matter are attracting e significant attention due to their important role in phase transition and their fascinating characteristics. Among the various types of matter, ferroics which possess a switchable physical characteristic and form domain structure are ideal systems to form topological defects.
