Structure of Olivine Phosphate

On a fundamental point of view, the main interest lies in the fact that the olivine stmeture generates geometric frustration of the magnetic interactions [92]. However, three olivine stmeture classes can be distinguished as a function of the site 

We use the structural data determined by Streltsov et al. [86] as a standard reference (Table 7.1). The orthorhombic unit cell of the olivine stmcture contains 28 atoms (Z = 4). Structural parameters and interatomic distances are listed in Tables 7.2 and 7.3. Fe-0 distances range from 2.064 to 2.251 A. The Fe-Fe separation in LiFeP04 is large (3.87 A).
