Bare Lithium Iron Phosphate (LiFePO 4 ), Cu, La doped and Cu with La co-doped LiFePO 4 composite materials have been prepared via polyol technique without further post heat treatment. The prepared bare and composite materials' crystalline structure has been indexed an orthorhombic phase olivine structure with space group of Pnma. The functional group vibrations and surface morphology of the prepared materials has been observed using Fourier transfer infrared spectroscopy (FT-IR) and scanning

Magnetization measurements revealed that saturation magnetizations (Ms) of the metal doped samples are gradually increased than that of the pure LiFePO 4 . All the samples exhibit the spin-glass behaviour of magnetic materials.
