Strong magnetoelectric (ME) interaction was demonstrated at both dc and microwave frequencies in a novel Zn 0.1 Fe 2.9 O 4 /PMN–PT (lead magnesium niobate–lead titanate) multiferroic heterostructure, which was prepared by spin-spray depositing a Zn 0.1 Fe 2.9 O 4 film on a single-crystal PMN–PT substrate at a low temperature of 90 °C. A large electric-field induced ferromagnetic resonance field shift up to 140 Oe was observed, corresponding to an ME coefficient of 23 Oe cm kV −1 . In addition, a large electrostatic field tuning of the magnetic hysteresis loops was observed with a large squareness ratio change of 18%. The spin-spray deposited ferrite/piezoelectric multiferroic heterostructures exhibiting strong ME interactions at both dc and microwave frequencies provide great opportunities for novel electrostatically tunable microwave magnetic devices synthesized at a low temperature.
