Wang, Meng, Zhao, Shengsheng, Zhang, Xiaolong, Huang, Changwei, Zhu, Yi.  2020.  Effect of La addition on structural, magnetic and optical properties of multiferroic YFeO3 nanopowders fabricated by low-temperature solid-state reaction method. 2020 6th International Conference on Mechanical Engineering and Automation Science (ICMEAS). :242–246.
Nanosize multiferroic La-doped YFeO3 powders are harvested via a low-temperature solid-state reaction method. X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectra analysis reveal that with La addition, YFeO3 powders are successfully fabricated at a lower temperature with the size below 60 nm, and a refined structure is obtained. Magnetic hysteresis loop illustrates ferromagnetic behavior of YFeO3 nano particles can be enhanced with La addition. The maximum and remnant magnetization of the powders are about 4.03 and 1.22 emu/g, respectively. It is shown that the optical band gap is around 2.25 eV, proving that La doped YFeO3 nano particles can strongly absorb visible light. Both magnetic and optical properties are greatly enhanced with La addition, proving its potential application in magnetic and optical field.
