Zr 4+ doped multiferroic LuFeO 3 (LFO) samples were prepared by a sol-gel reaction method and the effect of doping on structural, electric and magnetic properties are evaluated and compared with pure LFO. X-ray diffraction and Rietveld refinement confirm that the pure and Zr doped LFO exists in the hexagonal crystal structure with space group P6 3 cm . The unit cell parameters and the volume of Zr 0.2 Lu 0.8 FeO 3 (ZLFO) are greater than that of the undoped LFO. Magnetic measurements for ZLFO sample show a weak ferromagnetic-like behaviour at room temperature with M r ∼ 0.013 emu/g and finite coercivity. Hence, the paramagnetic LFO transformed to the weak ferromagnetic at room temperature upon Zr doping.
