Abstract

Multiferroic composites with combined ferromagnetic (FM) and ferroelectric (FE) phases have attracted extensive attention due to their strong magnetoelectric (ME) coupling at room temperature. This paper demonstrates large ferromagnetic resonance tunability through voltage induced, strain mediated ME coupling in LFO/PMNPT multiferroic heterostructures. A large effective magnetic anisotropy field change of 150 Oe was obtained, corresponding to a large ME coefficient of 12 .5 Oe cm/kV . LFO/PMNPT heterostructures have shown great potential for tunable RF/microwave device applications .
