Abstract

LaFeO₃ has been prepared using the solid-state reaction method with High Energy Milling (HEM). The preparation of LaFeO₃ was carried out using stoichiometric calculations. Based on the XRD measurement results, single-phase LaFeO₃ with an orthorhombic crystal structure was obtained. From the SEM results, the morphology of LaFeO₃ is uniform, and the EDS results show the weight percentage of La, Fe, and O elements are 49.74, 21.08, and 29.18 wt%, respectively. VSM LaFeO₃ results show magnetic saturation, remanence, and coercivity are 0.24 emu/g, 0.02 emu/g, and 853.38 Oe, respectively, and the absorption of LaFeO₃ is-7.40 dB at a frequency of 6.02 GHz with a LaFeO₃ sample thickness of 1.5mm.
