A “domain wall” denotes an interface or boundary separating distinct regions within a material, particularly noticeable in magnetic or crystallographic domains. In magnetism, these walls delineate zones where the magnetic orientation shifts between neighboring areas. They emerge in ferromagnetic materials or those with magnetic properties, marking transitions between regions with varying magnetic alignment. These walls significantly impact a material’s behavior, influencing properties like magnetization and the arrangement of magnetic domains. Understanding domain walls is vital in comprehending magnetic materials’ functionality, aiding in the manipulation of magnetic properties for technological applications in data storage, sensors, and magnetic devices. Their manipulation and control offer pathways for developing innovative materials and enhancing device performance in various fields of technology and science, making them a focal point of research in material science and condensed matter physics.
