Abstract Motivated by the fast-developing spin dynamics in ferromagnetic/piezoelectric structures, this work attempts to manipulate magnonics (spin dynamics) by the converse magnetoelectric (ME) coupling. Herein, electric field (E-field) tuning magnetism, especially the surface spin wave, is accomplished in Ni/0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 (PMN-PT) multiferroic heterostructures. The Kerr signal (∝magnetization) changes of Ni film are observed when direct current (DC) or alternative current (AC) voltage is applied to PMN-PT substrate, where the signal can be modulated breezily even with no extra magnetic field (H-field) is needed in AC-mode measurement. Deserved to be mentioned, an “1” (i.e., “on”) and “0” (i.e., “off”) surface spin wave switch upon applying an E-field is created at room temperature. In addition, the magnetic anisotropy of heterostructures has been investigated by E-field induced ferromagnetic resonance (FMR) shift, and a large 490 Oe shift of FMR is determined at the angle of 45° between H-field and heterostructure plane.
