Abstract
The indirectly induced magnetic fields at Sn4+ replacing Fe3+ in octahedral positions are derived in the MO LCAO [molecular orbitals by linear combinations of atomic orbitals] semiempirical approximation, with self-consistent charges on the atoms, for a part of the crystal containing Sn4+ and Fe3+ (in tetrahedral positions), the two being linked via oxygen ions. The absence of conduction is due to the very restricted overlap between the MO of the parts. The results explain the observed induced field and also predict certain possible effects, in particular unpaired spin density on other lattice ions.
