We have investigated Li0.8Na0.2FePO4, a cathode material for secondary battery applications, by using X-ray diffractometry (XRD), vibrating sample magnetometry (VSM) and Mössbauer spectroscopy. The crystal structure is found to be orthorhombic with lattice parameters of a 0 = 10.333 Å, b 0 = 6.011 Å and c 0 = 4.700 Å. From the temperature dependence of both the magnetization and the Mössbauer spectra, the Néel temperature is found to be T N = 51 K and the spin reorientation temperature to be T S = 20 K. The magnetic hyperfine field (H hf ), electric quadrupole splitting (ΔE Q ) and isomer shift (δ) at 4.2 K are found to be H hf = 130.50 kOe, ΔE Q = 2.63 mm/s and δ = 1.25 mm/s.
