Magnetic hysteresis loops are not exclusive to materials with ferromagnetic ordering.
2.
However, phenomena such as the magnetic hysteresis loops are mainly " rate-independent ", which makes possible a durable memory.
3.
Typically the coercivity of a magnetic material is determined by measurement of the magnetic hysteresis loop, also called the " magnetization curve ", as illustrated in the figure.

5.
The magnetic hysteresis loop of an exchange spring magnet theoretically takes on a shape resembling that of a summation of its hard and soft magnetic components ( as seen in Figure 1 ), meaning its " energy product " is higher than those of its components.
