Anomalous coercive force of Bloch point in iron single crystals
Zubov V. E. , Krinchik G. S. , Kuz'menko S. N.
The coercive field of a Bloch point near the surface of iron whiskers has been measured for the first time. This field is more than an order of magnitude greater than the coercive field of vertical Bloch lines and more than three orders of magnitude greater than the coercive field of a domain wall in the same crystal.
