in a way so as to minimize the magnetostatic energy. An example of such a domain pattern
for a single crystal of a cubic material is shown in Fig. 14.2.3.
A domain pattern of a similar nature is also present in a non-magnetized Ni–Fe alloy.
When no field is applied during the annealing treatment, the pair moments will become
aligned in the local field corresponding to the local magnetization in each magnetic domain.
