LuFeO_3 and Lu_(0.2)Y_(0.8)FeO_3 powder were prepared by solution combustion method using urea and glucose as fuels for the first time. Samples were characterized by X-ray diffraction, and results reveal that Lu_(0.2)Y_(0.8)FeO_3 has a dual structure consisting of an orthorhombic framework and a secondary hexagonal framework. The substitution of Y~(3+) in LuFeO_3 resulted in a reduction in the crystal size. These irregularities are directly responsible for the shifts in spin polarity due to them. When Y~(3+) ions partially substitute Lu~(3+) ions, both the temperature at which the Curie transition occurs and the temperature at which the spin reorientation transition occurs rise. The magnetization profiles exhibit significant variations as a function of temperature. It is common knowledge that orthorhombic magnetic systems, such as LuFeO_3, show a bifurcation and bulge at 76 K caused by spin-reorientation transition temperatures (TSR). The applied field strength of 500 Oe brings out that data spike. Because of the diamagnetic dopant effect, the ZFC and F.C. curves of Lu_(0.2)Y_(0.8)FeO_3 display a small amount of bifurcation in their behavior. The magnetization slowed as the temperature increased, and there was no phase transition between 2 and 300 Kelvin. When heated to higher temperatures, it undergoes a phase change that changes its magnetic properties from paramagnetic to antiferromagnetic. LuFeO_3 dielectric characteristics were studied across a broad frequency spectrum, ranging from 2 to 300 K, and temperatures between those extremes. Observations made as the system got closer to the spin reorientation transition included an increase in temperature across the board, a divergence in frequency ranges, and an increase in the dielectric constant (TSR). At 150 kilo hertz, the low-frequency dispersion begins to increase, and it will keep growing until it approaches 225 kHz. Magnetoelectric interaction can be identified by a slight bump close to the transformation from antiferromagnetic to paramagnetic. The loss tangent was used as an example to demonstrate the frequency dispersion.
