The cause of the hysteresis in ferroelectrics is mainly due to domain switch [8–18]. Many researchers have devoted to study the nonlinear hysteresis loops of ferroelectrics by considering the domain switch. In the literature, Hwang et al [19], Chen and Lynch [20] considered the effect on the events by doyinWhen an external magnetic field is applied to a ferromagnetic material such as iron, the atomic domains align themselves with it. Even when the field is removed, part of the alignment will be retained: the material has become magnetized. Once magnetized, the magnet will stay magnetized indefinitely. To demagnetize it requires heat or a magnetic field in the opposite direction. This is the effect t… events by design dawsonville
