摘要：

A new mathematical model is given for vibration of domain walls pinned down by dislocations present in a ferromagnetic crystal. The theory is extended to explain magnetic damping where the motion of pinned down domain walls is held responsible. The problem is seen from dynamical consideration and is solved by the powerful operational method which is quite elegant to explain different components of magnetic damping. In the absence of any external magnetic field and with low amplitude mechanical stressing only the microeddy current loss occurs which is discussed in detail.
