Abstract: (3063 Views)
In this paper the concentration effect of magnetic fluid (MF) nanoparticles with dimension of 10 nm was investigated for magnetic field sensing with a non-adiabatic tapered optical fiber (NATOF) sensor. Using a refractive index (RI) sensor based-NATOF embedded in MF, the sensitivity of magnetic sensor in the range of 0-25 mT was measured. The most intensity and wavelength sensitivity of magnetic field sensor for different nanoparticle concentrations from 0.01% to 0.12% was obtained 11.36×10-3 and 212 pm/mT, respectively.
