報告內容簡介:

Heterostructured film based magnetoelectric (ME) composites consist of piezoelectric (typically PZT) and magnetostrictive layers are highly desired especially for applications in integrated magnetic/electric devices. The thermal processing, necessary to obtain high quality PZT films with superior functional properties, unavoidably leads to surface oxidation and crystallization of amorphous magnetostrictive metal substrate, and also chemical interdiffusion between two phases. This will deteriorate both of their properties and eventually degrade the ME coupling. Using granule spray in vacuum process (GSV), PZT thick film was deposited on magnetostrictive amorphous metal (Metglas) substrate. The PZT film was annealed with a continuous-wave 560 nm laser radiation to minimize deteriorative effects of general thermal process, such as chemical reaction and/or atomic diffusion, at the interface and crystallization of amorphous Metglas substrate. We have accomplished near-theoretical magnetoelectric performance in laser annealed PZT/Metglas film composites. The thickness dependent dielectric, ferroelectric, and ME properties of the PZT/Metglas composites were found to be related to the corresponding changes in the optical band gap, annealing behavior and crystallization characteristics of the PZT films.
