Weiss domains

Weiss domains are specialized regions within a crystal structure where certain atoms or molecules are arranged in a consistent, repeating pattern. These domains represent areas with uniform orientation or magnetic alignment, which differ from neighboring regions. They are important in understanding a material's properties, such as its magnetic behavior or how it interacts with light. Essentially, Weiss domains are like "neighborhoods" inside a crystal, each with a specific internal order that influences the overall qualities of the material.
