A study of domain wall and magnetic domain changes in T bar by employing ferro-fluid and comparison of the results with magneto-optical Kerr effect measurements

The movements of domain walls and the changes in the magnetic domain patterns of a T bar are studied by employing Ferro-fluid and the results are compared with the model proposed for a T bar. The oscillation of the walls and the changes of the magnetic domains in T bar due to an oscillating in-plane field are shown by different sketches. The net magnetization distribution that can be obtained from these observations are compared to the similar results obtained by Krinchik et al.
