This work focuses on the fabrication of hybrid magnetoelectric heterostructures formed by magnetostrictive Ni90<\/sub>Fe10<\/sub> films electrodeposited on Y-cut 128\u00b0 LiNbO3<\/sub> (LN) piezoelectric substrates, a cut widely used for surface acoustic waves (SAWs). X-ray diffractometry (XRD) measurements with out-of-plane (OOP) applied voltage demonstrate the deformation of the magnetostrictive film despite the partial presence of nonpiezoelectric LiNbO2<\/sub> (LNO) in the substrates. Magneto-optical Kerr effect (MOKE) measurements reveal how the LN substrate induces an uniaxial in-plane (IP) magnetic anisotropy in the Ni90<\/sub>Fe10<\/sub> film with the easy axis along LN \u0305 and the hard axis along LN directions, respectively. Analysis of the strain tensor of the LN substrate confirms that the experimentally observed changes in the Ni90<\/sub>Fe10<\/sub> magnetostrictive layer are consistent with the mechanical deformation induced by the substrate. Voltage-dependent MOKE hysteresis loops show converse magnetoelectric couplings of   = (-0.10 \u00b1 0.02) \u03bcs\/m in the hard magnetic axis of the Ni90<\/sub>Fe10 <\/sub>layer, and  = (-0.16 \u00b1 0.01) \u03bcs\/m at 45\u00b0 with respect to it, despite the presence of the non-piezoelectric LNO secondary phase in the commercial substrate. The robustness of the magnetoelectric coupling is confirmed, exhibiting no visible degradation in the remanence signal after dozens of polarization cycles. These results evidence voltage control of magnetic anisotropy in the Ni90<\/sub>Fe10<\/sub>\/LN heterostructure, providing a low-cost, lead\u2011free system to control the magnetic axes.<\/p>\n
