Electric-poling-induced magnetic anisotropy and electric-field-induced magnetization reorientation in magnetoelectric Ni/(011) [Pb(Mg1/3Nb2/3)O3](1-x)-[PbTiO3]x heterostructure

“…1,2 The converse magnetoelectric effect (CME), i.e., magnetization change by an applied electric field, offers substantial promise for a wide range of applications, such as highly sensitive magnetometers, 3 tunable inductors, 4 nanoscale electromagnet, 5 and magnetic random access memory (MRAM). 6,7 Several studies have reported that electric-field-induced strain, [8][9][10][11][12] especially a large anisotropic strain, [13][14][15][16] can alter the magnetic properties of ferromagnetic materials.…”

Recent Progress in Multiferroic Magnetoelectric Composites: from Bulk to Thin Films

“…Large FMR frequency shifts have been observed in several types metglas-based ME composites, [74][75][76][77] as the metglas have the high saturation magnetization, low saturation magnetic fi eld, and relatively low FMR linewidth, in comparison to traditional ferrites [e.g., yttrium iron garnet (YIG) and Fe 3 O 4 ]. For instance, shifts of 50-110 MHz at ∼ 2.3 GHz for FeCoB/PZT or FeGaB/PZT laminate, [ 74 ] and 210 MHz at 9.5 GHz for metglas/PZT fi bers layer [ 77 ] by applying electric fi elds to PZT, were reported. The piezo-strain induced in PZT leads to a change in the in-plane anisotropy fi eld of the metglas due to the converse magnetoelastic effect, which is refl ected to the shift in the FMR frequency of the magnetic fi lms at microwave frequencies.…”

Strain Mediated in‐Plane Uniaxial Magnetic Anisotropy in Amorphous CoFeB Films Based on Structural Phase Transitions of BaTiO3 Single‐Crystal Substrates

“…It is well known that the magnetic properties of ferromagnetic films (FM) can be tuned as a result of interfacial strain coupling in heterostructures. In many cases, the interfacial strain is mechanically applied using piezoelectric systems powered by electricity . Such systems have recently attracted considerable attention because of their potential applications in spintronic devices.…”
