Bloch wall

[′bläk ‚wȯl]
(solid-state physics)
A transition layer, with a finite thickness of a few hundred lattice constants, between adjacent ferromagnetic domains. Also known as domain wall.

As shown in this figure, crystallites are divided by Bloch walls. In fact Bloch wall is a layer that separates neighbor domains with different magnetic directions.
It is expected that increase in milling time leads to increase saturation magnetization, because it will reduce the size of magnetic particles and total number of Bloch walls will also decrease.
The hard/soft/hard one forms two 180[degrees] Bloch domain walls while the soft/hard/soft one forms a 360[degrees] Bloch wall due to the exchange-coupled effect.
These are called Bloch walls or Neel walls, depending on the plane in which the rotation of magnetic direction takes place.
