• , and is usually accompanied by an increase of coercivity (Hc) and of the blocking temperature (TB). The EB was first described by Meiklejohn and Bean in 1956 [4]. They investigated clusters with a FM cobalt core and an AFM cobalt oxide (CoO) shell and consequently observed the characteristic horizontal

• decrease of the olivine impurities and in an increase of the fluorophosphate constituent. The formation of the almost pure Li2Co0.7Fe0.3PO4F was observed upon heating at 740–750 °С. Above these temperatures (>760 °С) samples melted and were heavily contaminated by cobalt oxide. Thus, the annealing at 750
