A 2-2 type multiferroic composite device encompassing three CoFe₂O₄ (CFO) layers confined between four Pb_0.99[Zr_0.45Ti_0.47(Ni_1/3Sb_2/3)_0.08]O₃ (PZT) layers was fabricated by tape casting. X-ray diffraction data showed good chemical compatibility between the two phases, whereas Scanning Electron Microscopy imaging also revealed an intimate contact between CFO and PZT layers. Under an applied electric field of 65 kV/cm, this multilayer device shows a saturated polarisation of 7.5 μC/cm² and a strain of 0.12%, whereas under a magnetic field of 10 kOe it exhibits a typical ferromagnetic response and a magnetic moment of 33 emu/g. This device can be electrically poled, after which it exhibits magnetoelectric coupling.

通过胶带制造了包含三个CoFe ₂ O ₄（CFO）层的2-2型多铁性复合器件，该层限制在四个Pb _0.99 [Zr _0.45 Ti _0.47（Ni _1/3 Sb _2/3）_0.08 ] O ₃（PZT）层之间铸件。X射线衍射数据显示了两相之间的良好化学相容性，而扫描电子显微镜成像也显示了CFO和PZT层之间的紧密接触。在65 kV / cm的施加电场下，该多层器件显示出7.5μC/ cm ²的饱和极化应变为0.12％，而在10 kOe的磁场下，它表现出典型的铁磁响应和33 emu / g的磁矩。该装置可以被电极化，之后呈现出磁电耦合。
