This is achieved by various hot and cold rolling stages to produce textured sheets, known as grain-oriented silicon-steel, with the [001] direction in the length of the lamination. The <001> type crystal directions are the easy directions of magnetisation and hence the ...

In case of grain boundaries, since they exhibit high energy compared to the bulk material, they are preferentially dissolved when the sample contacts with the reactive resulting in the formation of cracks among the valleys (Figure 2).
