摘    要:
Magnetic properties and crystal symmetry of electrochemical material LiFePO4 have been investigated by Moessbauer spectroscopy and magnetization measurement. Magnetization reveals the antiferromagnetic nature of LiFePO4. Temperature dependence of inverse susceptibility and that of hyperfine field confirm that there is an antiferromagnetic-paraxaagnetic transition at about 50K.

Abstract:
Magnetic properties and crystal symmetry of electrochemical material LiFePO_{4} have been investigated by M?ssbauer spectroscopy and magnetization measurement. Magnetization reveals the antiferromagnetic nature of LiFePO_{4}. Temperature dependence of inverse susceptibility and that of hyperfine field confirm that there is an antiferromagnetic-paramagnetic transition at about 50K.
Keywords:lithium-polymer battery  M?ssbauer spectroscopy  lithium iron phosphates
