The magnetoelectric coupling effect of NZFO/PZT thin film heterostructures was investigated by tuning the Zn content in the NZFO film. The highest magnetoelectric coupling coefficient was achieved at x = 0.15, indicating the importance of Zn content in influencing the magnetoelectric properties.
Magnetoelectric coupling effect of Ni1-xZnxFe2O4/PZT (NZFO/PZT) thin film heterostructures is investigated by tuning the Zn content in NZFO film. The highest magnetoelectric coupling coefficient of NZFO/PZT heterostructures is achieved at x = 0.15 with the value of 328 mV/cm Oe. This various magnetoelectric effect in NZFO/PZT heterostructures with different Zn content is induced by distinct magnetostriction of NZFO film, which is related to piezomagnetic coefficient q and the initial permeability mu(i) of NZFO layer, as well as the exchange interaction of ions at tetrahedral and octahedral sites. This study is of helpful for understanding the magnetoelectric effects of epitaxial magnetoelectric heterostructures that involves NZFO ferrite films. (C) 2021 Elsevier B.V. All rights reserved.
