Equations (3.11) and (3.12) are valid for any inclination of the st-Bloch line,
considering a to be measured perpendicular to the line. If the Bloch line lies
parallel to the film plane, it is called a horizontal Bloch line. The gradient of H,
then implies ...

Interactions between Bloch lines. – Two principal interaction mechanisms
between Bloch lines arise from magnetostatic and exchange energies
respectively. With respect to magnetostatic energy, which dominates at long
distances, fig.

Bloch line is [42] (7.8) F = (24 My) V, x t + [4x ME,(H,)|y|Q' E,(0)]V., where t = a unit
vector (with direction W4 × V0) tangent to the Bloch line, and E.(H,) is the Bloch-
line energy [14, 19]. A Bloch line is called positive or negative according to the ...
