Paper Abstract

The first experimental observation of the acoustically induced d.c. magnetization (acousto- magnetic effect (AME)) is reported for intense surface acoustic waves (SAW) in a layered structure LiNbO3 - FeMoP. An amorphous magnetostrictive film exhibited a strong magnetoacoustic (MA) nonlinear behavior under the MA-resonance (MAR) conditions at extremely low magnetic field 30 Oe for 30- MHz MASAW. Transversal AME observed in the experiment was found to be even on MASAW propagation direction and odd in respect to a bias magnetic field orientation. A feasibility of AME applications for a high-sensitive scanning magnetic field sensor was demonstrated.
