Domain structure of the single crystal hexagonal ferrite, Co/sub 2/X

Domain structure of the single crystal hexagonal ferrite, Co/sub 2/X

Domain patterns on both basal and axial surfaces of single crystals of the hexagonal ferrite Ba/sub 2/Co/sub 2/Fe/sub 28/O/sub 46/ have been studied with the Bitter technique. Patterns on the basal sections show a well-defined six-fold symmetry with 60 degrees , 120 degrees , and 180 degrees walls....

Zusammenfassung:Domain patterns on both basal and axial surfaces of single crystals of the hexagonal ferrite Ba/sub 2/Co/sub 2/Fe/sub 28/O/sub 46/ have been studied with the Bitter technique. Patterns on the basal sections show a well-defined six-fold symmetry with 60 degrees , 120 degrees , and 180 degrees walls. Surfaces containing the c-axis show unusual features. It is suggested that the overall domain behavior is best explained by assuming that the ferrite has an easy cone with a large semiangle.< >
