Title:
MAGNETIC ELASTIC SURFACE WAVE MUTUAL OPERATING DEVICE
Document Type and Number:
Japanese Patent JPS5478054
Kind Code:
A
Abstract:
The invention relates to an interaction device comprising a non-magnetic substrate, a thin easy-plane magnetic layer, two piezoelectric transducers arranged at the ends of the magnetic layer and respectively receiving the two electrical signals to be treated. The signals applied are converted into elastic surface waves which are transmitted to the magnetic layer in the form of magnetoelastic waves propagated in opposite directions. The device is subjected to an external magnetic field. The variations in magnetization in the interaction zone are collected by a detection plate and characterize the interaction between the two signals.
