Experimental observation of "Bloch-point" features in a domain wall
Zubov V. E. , Krinchik G. S., Kudakov A. D.
A magnetooptic method has been used to study the fine structure of a Bloch wall at the surface of iron single crystals. This fine structure is unambiguously related to the direction of the asymmetric curvature of the wall near the surface. Structural features of the Bloch-point type have been seen for the first time in an asymmetric Bloch wall.
