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.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
