FERROELECTRIC MATERIALS, HYSTERESIS CURVE AND SPONTANEOUS POLARIZATION

In ferroelectric materials, the polarization P does not vary linearly with electric field E. Hysteresis curve: The plot of P versus E in which the material is polarized in one direction and then in opposite direction is called the hysteresis … Continue reading

Coercivity

Coercivity is defined as the value of the magnetising field at which the intensity of magnetisation becomes zero. It is also known as coercive field. Hence, the coercivity of a material is a measure of the strength of the reverse … Continue reading
