The invention discloses a nanometer LiZn ferrite material. A mole ratio of Fe(NO3)3.9H2O to Zn(NO3)2.6H2O to LiNO3 is (42-48):(5-7):(6-8); a mole percentage of C6H8O7.H2O is 48-54% based on a mole sum of NO<3><-> of Fe(NO3)3.9H2O, Zn(NO3)2.6H2O and LiNO3; and the mass percentage of Bi2O3 is 0.6-0.7% based on a mass sum of Fe(NO3)3.9H2O, Zn(NO3)2.6H2O, LiNO3, and C6H8O7.H2O. The nanometer LiZn ferrite material is prepared by preparing a matrix solution from Fe(NO3)3.9H2O, Zn(NO3)2.6H2O, LiNO3, and water; preparing a complexing agent solution from C6H8O7.H2O and water; mixing the matrix solution and the complexing agent solution and adding Bi2O3; adjusting a pH value to obtain a mixed solution; stirring the mixed solution at a constant temperature to obtain sol; drying the sol to obtain xerogel; performing self-propagating combustion; and performing moulding and sintering.
