Multiferroic and magnetoelectric properties of Pb0.99[Zr0.45Ti0.47(Ni1/3Sb2/3)0.08]O3–CoFe2O4 multilayer composites fabricated by tape casting
A 2-2 type multiferroic composite device encompassing three CoFeO (CFO) layers confined between four Pb[ZrTi(NiSb)]O (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 reveal...

| Resumo: | A 2-2 type multiferroic composite device encompassing three CoFeO (CFO) layers confined between four Pb[ZrTi(NiSb)]O (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/cm 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. |
