Pressure-Dependence of Magnetic Coupling in Ionic Solids from Ab-Initio Cluster Model-Calculations
The dependence of the magnetic coupling constant, J, with the pressure has been studied by an ab initio cluster model approach in a typical ionic solid such as KNiF3. By computing J at different values of the lattice parameter R, we predict a power law of the form J approximate to R(-n) with 10.5
