摘要

Magnetic properties and crystal symmetry of electrochemical material LiFePO4 have been investigated by Mossbauer 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-paramagnetic transition at about 50K.
