Diminution of eddy-current losses in propagation of magneto-acoustic-wave in quasiperiodic multilayers

In order to reduce the eddy-current losses in the highly magnetostrictive amorphous film for constructing magneto-surface-acoustic wave (MSAW) devices, an effective method was developed with insertion of insulating layers in the film. In this paper, we present the numerical results of the propagation properties of Love-type MSAW in a new type of modulated structures.
