Abstract: LaMn0.5Cu0.5O3 synthesized via sol-gel auto combustion method is found to having ferromagnetic ground state. The sample crystallizes in orthorhombic Pbnm space group with lattice parameters (in Angstrom) a = 5.4811(4), b = 5.5236(4), c = 7.7668(6). Evidence of Griffith’s singularity is observed in magnetic susceptibility data. The Griffith temperature (TG) and the exponent (GP) of modified Curie – Weiss law are found to be 36K and 0.984 respectively
