Condens. Matter 2019, 4, 86 8 of 15 Figure 5. The 57Fe Mössbauer spectrum of LiFePO4 above Néel temperature at T = 60 K. Figure 6. The 57Fe Mössbauer spectrum of LiFePO4 at liquid helium temperature (T = 4.2 K, Bext = 0 T). The inset shows the distribution of Bhf at the nuclei. The in-field Mössbauer spectrum of LiFePO4 at T = 4.2 K and Bext = 6 T is presented in Figure 7. The application of the external field provokes a broadening of the octet O lines due to the vectorial sum of randomly oriented local Bhf and the applied external field Bext perpendicular to the γ-ray direction. The average value of the polar angle θ ∼ 13◦, see Table 1, and a higher probability above the mean value of Bhf, see inset in Figure 7, indicates the canting of the Fe2+ moments arranged originally antiferromagnetically. In fact, there are four nonequivalent Fe ion sites with respect to hyperfine interactions when an external magnetic field is applied. Since the single Fe ion magnetic anisotropy is strong, which is explained below, the external field does not cause significant deviation of the Fe ion MMPDF Image | Mossbauer Spectroscopy of Triphylite (LiFePO4) at Low Temperatures
