Abstract

Promising application after synthesis of Fe3O4 nanoflowers to stimulate magnetic field detection in large dynamic range using microfiber approach is presented. Technology relevant aspects of present study and current limitations are also highlighted. Earlier developed sensors for the magnetic field detection using magnetic fluid covers up to around 400 mT, which limits the application for higher magnetic field sensing. In this letter, we proposed for the first time a microfiber-based magnetic field sensor in the range from 0 to 1.5 Tesla by optimizing the coating of prepared Fe3O4 magnetic nanoflowers around the sensing probe. The interaction between modes of tapered fiber and magnetic nanoflowers coated on the probe, shift the interference pattern on the application of applied magnetic field. This facilitates in providing larger operating range to the device which can be used in magnetic resonance imaging for online monitoring of magnetic field.
