domain wall
A "domain wall" is a boundary separating regions of different states or orientations, found in various scientific fields such as physics, cosmology, and materials science.
Definition
C1Magnetism
(technical, academic)A boundary in a magnet where the direction of the magnetic field changes from one domain to another.
Example
- The domain wall in the magnet was observed using advanced imaging techniques.
- Understanding domain walls is crucial for developing better magnetic storage devices.
C2Cosmology
(theoretical, academic)A hypothetical two-dimensional defect in space-time that could have formed during phase transitions in the early universe, separating regions of different vacuum states.
Example
- The concept of domain walls helps explain certain features of the cosmic microwave background radiation.
- Researchers study domain walls to understand the evolution of the early universe.
C1Materials Science
(technical, academic)A region within a ferromagnetic or ferroelectric material where the direction of magnetization or polarization changes from one domain to another.
Example
- The domain wall movement in ferroelectric materials is critical for their functionality in memory devices.
- Scientists are exploring ways to manipulate domain walls to improve material properties.
