Multiferroics: different routes to magnetoelectric coupling

npj Spintronics
The simultaneous presence of ferroelectricity and magnetism in multiferroics breaks both spatial inversion and time reversal symmetries at the macroscopic scale, which opens the door to many interesting phenomena and resembles the violation of these ...

Thermomechanics of multiferroics

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
Generally understood ferroic media have been investigated by many authors. The majority of them have dealt with the electromagnetic nature of the domain structure of crystalline or amorphous solids.

Multiferroic quantum criticality [PDF]

Nature Materials, 2018
The zero-temperature limit of a continuous phase transition is marked by a quantum critical point, which can generate exotic physics that extends to elevated temperatures. Magnetic quantum criticality is now well known, and has been explored in systems ranging from heavy fermion metals to quantum Ising materials.

Characterization of Multiferroic Domain Structures in Multiferroic Oxides [PDF]

Journal of Nanomaterials, 2015
Multiferroic oxides have been received much attention due to that these materials exhibit multiple ferroic order parameters (e.g., electric polarization in ferroelectrics, magnetization in ferromagnetics, or spontaneous strain in ferroelastics) simultaneously in the same phase in a certain temperature range, which offer an exciting way of coupling ...

Multiferroic Hysteresis Loop [PDF]

Materials, 2017
Multiferroics, showing both ferroelectric and magnetic order, are promising candidates for future electronic devices. Especially, the fundamental understanding of ferroelectric switching is of key relevance for further improvements, which however is rarely reported in literature. On a prime example for a spin-driven multiferroic, LiCuVO4, we present an

Spintronics with multiferroics

Journal of Physics: Condensed Matter, 2008
In this paper, we review the recent research on the functionalization of multiferroics for spintronics applications. We focus more particularly on antiferromagnetic and ferroelectric BiFeO3 and its integration in several types of architectures.

Dynamical multiferroicity

Physical Review Materials, 2017
An appealing mechanism for inducing multiferroicity in materials is the generation of electric polarization by a spatially varying magnetization that is coupled to the lattice through the spin-orbit interaction. Here we describe the reciprocal effect, in which a time-dependent electric polarization induces magnetization even in materials with no ...

Multiferroic PbFe12O19 ceramics [PDF]

Journal of Electroceramics, 2011
PbFe12O19 (PFO) powders in hexagonal structure have been synthesized by sol-gel process using lead acetate, glycerin and ferric acetylacetonate as the precursor. PbFe12O19 ceramics were obtained by sintering the PbFe12O19 powders at 1000\degree C for 1 hour.

Multiferroic Rhodium Clusters

Physical Review Letters, 2014
Simultaneous magnetic and electric deflection measurements of rhodium clusters (Rh(N), 6 ≤ N ≤ 40) reveal ferromagnetism and ferroelectricity at low temperatures, while neither property exists in the bulk metal. Temperature-independent magnetic moments (up to 1 μ(B) per atom) are observed, and superparamagnetic blocking temperatures up to 20 K ...

γ-BaFe2O4: a fresh playground for room temperature multiferroicity

Nature Communications, 2022
The application of multiferroics is often limited by low ordering temperatures. Here, the authors show that BaFe2O4 is a room temperature antiferromagnet with improper ferroelectricity, suggesting it as a playground for the study of multiferroicity.
