英文摘要 | A modified polyacrylamide gel route was used to fabricate YMnO3 nanoparticles. In this route, the aqueous solution of inorganic Y and Mn salt was gelled by using acrylamide; during the gelation process, acrylamide was polymerized to form a polymer network, which provided a structural framework for the growth of particles. The X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry analysis, and Fourier transform infrared spectroscopy were used in combination to investigate the thermal decomposition process of xerogel and the formation of YMnO3 phase. It is demonstrated that high-purity YMnO3 powders can be prepared at a calcining temperature of 800 °C, which is nearly 300 °C lower than the synthesis temperature based on the solid-state reaction method. The scanning electron microscopy observation reveals that the prepared YMnO3 powder has a uniform particle size, and the particles are almost spherical. The magnetic hysteresis loop measurement shows that YMnO3 nanoparticles exhibit weak ferromagnetism at room temperature, which is different from the magnetic property of bulk samples. |
