Abstract
New anisotropic and highly magnetostrictive (λ = 507 ppm) Co(II)Fe(III)[sbnd]O(OH) nanosheets were synthesized by a coprecipitation method using a modified gas-slugs microfluidic system. The magnetostrictive response of the Co(II)Fe(III)[sbnd]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. The observed anisotropy in the magnetoelectric (ME) magnetic sensing mechanism combined with a new highly magnetostrictive Co(II)Fe(III)[sbnd]O(OH) nanostructures and good linearity of the developed ME sensor (r2 value = 0.995) not only allows the tailoring of the ME response for anisotr..
