Summary
Researchers confined multiferroic domains into domain walls, enabling control over unique properties. This breakthrough allows reversible switching between bulk and wall states using fields.
Area of Science:
- Condensed Matter Physics
- Materials Science
Background:
- Systems with long-range order, like ferromagnets, have domains separated by domain walls.
- Domain walls can exhibit unique properties distinct from the bulk material.
- Controlled manipulation of these properties between bulk and wall states is challenging.
Purpose of the Study:
- To demonstrate the controlled confinement of multiferroic domains into domain walls.
- To achieve a reversible interconversion between bulk and domain wall properties.
- To explore applications in multiferroic and antiferromagnetic systems.
Main Methods:
- Utilizing multiferroic Dy0.7Tb0.3FeO3.
- Confining multiferroic domains into domain walls within a non-multiferroic environment.
- Applying magnetic or electric fields to control the transformation.
Main Results:
- Successfully confined multiferroic domains into specific domain walls.
- Demonstrated the reversibility of this confinement process.
- Showcased field-induced control over the domain-to-domain wall transformation.
Conclusions:
- Achieved controlled interconversion of multiferroic order between bulk domains and domain walls.
- Established a method for manipulating domain wall properties.
- Opened new avenues for studying and controlling antiferromagnetic domain structures and topological defects.

Materials like iron, nickel, and cobalt consist of magnetic domains, within which the magnetic dipoles are arranged parallel to each other. The magnetic dipoles are rigidly aligned in the same direction within a domain by quantum mechanical coupling among the atoms. This coupling is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. However, some materials have weaker coupling, and are ferromagnetic at lower...

18.9K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

13.6K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

1.5K
The conduction of free electrons inside a conductor is best described by quantum mechanics. However, a classical model makes predictions close to the results of quantum mechanics. It is called the theory of metallic conduction.
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...
