MAGNETOELECTRIC EFFECT IN LAMINATED STRUCTURES WITH COMPOSITE AMORPHOUS ALLOY/THIN FE-CO-GA THIN FILM MAGNETOSTRICTIVE STRUCTURES
The magnetoelectric effect (ME) in laminated structures of the type graded composite magnetostrictive ferromagnet / ferroelectric / composite magnetostrictive ferromagnet were investigated. Grading of composite layers was carried out by pulsed laser deposition of thin film layers of the Fe0.62Co0.19Ga0.19 magnetostrictive material. The morphology of thus obtained layers and magnitude of ME on the dc and ac magnetic fields were studied in the frequency range from 20 Hz to 10 kHz. It is shown experimentally that grading with the magnetostrictive film lowers the maximum value of ME in the whole frequency range investigated.
