Nickel Ferrite Nano fluid Functionalized Tapered Microfiber Based Magnetometer

Abstract Considering the promising utility of devices operating for high magnetic fields in noninvasive medical diagnostic applications such as resonance imaging, a microfiber-based magnetometer an extensive dynamic range actuated via NiFe 2 O 4 ferrite fluid is presented and proposed first time this paper. nanoparticles with mean diameter 37 nm (derived from Debye–Scherer’s formula) are prepared usingthe sol-gel process to fabricate magnetometer. Various scientific approaches utilized explore these nanoparticles’ structural, optical, morphological, features. Optimized lower concentration (~2%) nanofluid used surrounding environment fiber interferometer measure field up ~ 600 mT. The sensor can detect diverse maximum sensitivity 18 pm/mT. reported be extended further by applying voltage source finer tunability.
