Abstract

An X-ray diffraction technique utilizing a synchrotron radiation source has been proposed and implemented to study the processes of magnetic domain structure evolution in external fields. Highly perfect single crystals of iron borate FeBO3 were used as model objects. A series of  X-ray and magneto-optical experiments was 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 where direct observation of domains by magneto-optical and electron-microscopic methods is hindered.
