Direct synchrotron x-ray topography of moving domain walls in Fe : Si single crystals

Abstract

A real-time x-ray topography study of moving magnetic domain walls in an Fe : Si single crystal has been performed with double-crystal setting at the synchrotron radiation laboratory LURE. The domain walls were driven by a low-frequency magnetic field and viewed directly by means of a television detector system. Wall locking as well as wall bowing, the latter implying charged walls, have been observed.
