| Abstract: | Interaction models between domain walls and external field, lattice and defects as well as the interaction among domain walls are proposed. The dielectricloss, the dielectric constant and the internal friction (f=1KHz to 10KHz)associated with domain walls are explained systemically on the basis of these models. A comparison is made between the theoretical and experimental results on the dielectric loss. |
