Abstract

Iron nanosheet has been prepared in the presence of N-Methylaniline by solvothermal method. The structural property of the sample has been studied by X-ray diffraction and transmission electron microscopy. The magnetic properties have been extensively investigated by hysteresis loops and temperature-dependent magnetization curves. XRD result exemplifies that the as-prepared product has been identified as iron with body centered cubic structure. TEM observation showed that the as-prepared product composed of sheet-like nanostructure with size was around 25 nm. FTIR result suggests that the N-Methylaniline molecules are on the surface of the Fe Nano sheet. Magnetic measurements showed that the prepared iron nanosheet was ferromagnetic behavior at 300 K. Compared with bulk iron, Fe nanosheet exhibits significant increase in coercive force due to the presence of shape anisotropy. Moreover, the temperature dependent magnetization curves show no blocking temperature up to 300 K, which indicates the prepared sheet, is ferromagnetic character at room temperature.
