Abstract

An X-ray diffraction technique using a synchrotron radiation source has been developed and implemented to study the evolution processes of magnetic domain structure in external fields. High-quality single crystals of iron borate FeBO3 were chosen as model objects. A series of X-ray and magneto-optical experiments were performed to investigate the evolution of the magnetic domain structure in weak external magnetic fields. It has been established that the movement of domain walls leads to a stepwise broadening of the diffraction reflection curves of FeBO3 crystals. It is demonstrated that X-ray diffraction studies of the magnetic domain structure can be useful for characterizing magnetic materials in which direct observation of domains by magneto-optical and electron-microscopic methods is difficult.
