Lithium-Ion Conductors of the System LiCo1-xFexO2, Preparation and Structural Investigation

For magnetic solids with several unpaired spins per spin site, the average spin orbital interaction energies and the average spin orbital interaction energy squares <(e)2> were defined as a qualitative measure for the strengths of their antiferromagnetic spin exchange interactions. The trends in the antiferromagnetic spin exchange interactions of the magnetic solids containing MnF5 chains and CrX2 (X=O, S) layers were examined in terms of the and <(e)2> values calculated for their spin dimers.
