Resumo(s): | Anisotropic and highly magnetostrictive (λ=507 ppm) Co(II)Fe(III)-O(OH) nanosheets were synthesized as a novel elements for the development of magnetic sensors. Further, their applicability is demonstrated by the development of magnetic sensors based on the magnetoelctric (ME) effect of flexible polymer based Co(II)Fe(III)-O(OH)/P(VDFTrFE) composites. . The magnetostrictive response of the Co(II)Fe(III)-O(OH) nanosheets, when coupled to the piezoelectric response of P(VDF-TrFE), d33=-30±1 pC.N-1 , leads to a maximum magnetoelectric coupling α31 of 5.10 mV.cm-1 .Oe-1 . Furthermore, magnetic filler orientation within the polymer matrix allow a quasisinusoidal ME response of the composite as a function of the angle between HDC and Co(II)Fe(III)-O(OH) length direction. Such anisotropy in the ME magnetic sensing mechanism combined with a new highly magnetostrictive Co(II)Fe(III)-O(OH) nanostructure and the good linearity of the developed ME sensor (r 2 value =0.995) allows the tailoring of the ME response for anisotropic magnetic sensing device applications such as digital compasses or GPS devices |
