The magnetization distribution in elements of bubble domain chevron detector is first investigated using the magnetooptical micromagnetometer technique. Distribution curves of in-plane magnetization components are obtained in all types of elements. It is found that the magnetization distribution in elements having interconnections is very different from those having none. It is shown that the magnetization distribution in a chevron which is in row, is not equivalent to the one beyond it. It is shown that the magnetization component on the chevron leg perpendicular to the field is more than zero and amounts to Msat the center of the chevron. Fields are determined in which there are remagnetization and redistribution of magnetization in bubble domain chevron detector.
