Abstract
The temperature dependence of the hyperfine fields corresponding to ferric ions in the different sublattices of BaLiFe17O27 W-type hexagonal ferrite has been measured. A mean field analysis of these sublattice magnetizations has been done and a set of nearest neighbour isotropic exchange interactions has been obtained. The relative strenght of these fitted exchange values is in accordance with superexchange theory
