Abstract/Summary:
lectrical energy storage in a dielectric material is given by ;Initially, phase transitions with respect to temperature were studied to assist in understanding the relative AFE and FE phase stabilities, and phase diagrams plotted. The onset of diffuse phase transitions (DPTs) occurred more readily due to La;A strong correlation was observed between W;A value of...
