Abstract

New anisotropic and highly magnetostrictive (k = 507 ppm) Co(II)Fe(III)AO(OH) nanosheets were synthesized by a coprecipitation method using a modified gas-slugs microfluidic system. The magnetostrictive response of the Co(II)Fe(III)AO(OH) nanosheets, when coupled to the piezoelectric response of P(VDF-TrFE), d33 = 30 ± 1 pCN1 , leads to a maximum magnetoelectric coupling a31 of 5.10 mVcm1 Oe1 . The observed anisotropy in the magnetoelectric (ME) magnetic sensing mechanism combined with a new highly magnetostrictive Co(II)Fe(III)AO(OH) nanostructures and good linearity of the developed ME sensor (r2 value = 0.995) not only allows the tailoring of the ME response for anisotropic polymer-based device applications such as digital compasses or GPS devices but also open new application directions such as actuators and in the biomedical field.
