We report the structural and magnetic characterization of the polycrystalline LaFe0.5Mn0.5O3 compound. It crystallizes in an orthorhombic crystal structure with Pnma space group. A systematic investigation of magnetic behavior revealed the antiferromagnetic ordering at 276 K and Griffiths Phase-like behavior in the temperature range of 276 K to 314 K, confirmed by the power-law susceptibility exponent(λ). At a low temperature, spontaneous magnetization (Ms) is due to dominant ferromagnetic interaction. We estimated the magnitude using Arrot plot of different isotherms.
