Systematic investigation of MF3 crystalline compounds (M=Al, Cr, Fe, Ga, In, Sc, Ti, and V) and Fe1−xMxF3 mixed series (M=Ga, Cr, V)

The electric field gradient at the fluorine site of several crystalline trifluorides was measured by means of the time differential perturbed angular distribution method. The hyperfine data (ν Q and η) are systematically analyzed by taking into account the structural parameters of the crystals; they are also compared to the results obtained by point charge calculations
