Magnetization of lithiated magnetite, LixFe3O4

It is shown that annealed lithiated magnetites LixFe3O4, with x less than or equal to 0.60, present a regular Fe distribution between octahedral and tetrahedral sites. Their saturation magnetisation, remanent magnetisation and coercive field change linearly as a function of the lithium concentration...

Zusammenfassung:	It is shown that annealed lithiated magnetites LixFe3O4, with x less than or equal to 0.60, present a regular Fe distribution between octahedral and tetrahedral sites. Their saturation magnetisation, remanent magnetisation and coercive field change linearly as a function of the lithium concentration. Non-annealed materials present a non-regular Fe distribution due to interstitial Li ions. 13 refs.
