Integration of nanoparticles into polymeric materials enhances the optical properties and stability of the formed nano-composite materials. In this work, magnetic iron oxide nanoparticles Fe3O4NPs were prepared via chemical coprecipitation. In addition, it is polymerized in a host of polyvinylpyrrolidone PVP. The prepared iron oxide nano-size was about 14.0 nm as confirmed by Transmission Electron Microscopy, A vibrating sample magnetometer VSM studies showed Fe3O4NPs possess superparamagnetic behavior. Energy-dispersive X-ray spectroscopy, and X-ray diffraction confirmed the structure and composition of Fe3O4NPs. Open aperture Z-scan and optical limiting experiments were carried out at nanosecond pulses of wavelength 532 nm. The nonlinear absorption coefficients were calculated for the colloidal and polymeric iron oxide. Fe3O4NPs polymeric film exhibits enhanced nonlinear optical properties NLO, and superior optical limiting properties compared to Fe3O4NPs colloidal solution. That makes Fe3O4 nanocomposites a promising candidate for optical limiting applications.

In this study, a high-sensitivity intensity-interrogated fiber sensor integrated with ferrofluids is proposed for the measurement of a weak magnetic field (MF) with resolved temperature cross-sensitivity. The MF sensor is fabricated simply by an offset tapering single-mode fiber concatenated with a multimode fiber (MMF), which is then encapsulated into a capillary tube filled with ferrofluids. In the presence of MMF, stronger mode coupling could be achieved over the S-tapered fiber region. Its spectral response to variations in the applied MF intensity and ambient temperature have been investigated in detail. The proposed sensor shows a high MF sensitivity up to − 0.1130 d B / O e for the measurement range of 40 to 120 Oe, which, to our best knowledge, is higher than other previously reported MF sensors. And moreover, the measurement errors caused by temperature cross-sensitivity have been corrected by using a sensing matrix for the temperature range of 25°C to 35°C. Our proposed MF sensor possesses the advantages of high sensitivity, low cost, and applicability for applications in weak MF measurements.
