Sub-wavelength extreme ultraviolet microscopy reveals domain-wall stability during ultrafast demagnetization

Scientists have developed a new microscopy technique using sub-wavelength extreme ultraviolet (EUV) light to observe magnetic domain walls. This advanced method allowed researchers to investigate the behavior of these domain walls during ultrafast demagnetization processes. The findings indicate that domain walls remain remarkably stable even when subjected to extremely rapid changes in magnetization.

Understanding the stability of magnetic domain walls under rapid demagnetization is crucial for developing next-generation high-speed magnetic data storage and processing technologies.
