The magnetic properties and EPR spectra of magnetically diluted KNixMg1−xF3 perovskite solid solutions are examined. The susceptibility measurements show that these compounds are isotropic antiferromagnetic materials at high nickel concentrations. A critical concentration is found to be x = 0.4. The relation of resonance linewidth versus temperature within a temperature range of 100 to 400 K is linear. The relationship of resonance linewidth versus temperature and the concentration of magnetic ions are analyzed with Huber's Hamiltonian including a modulation by lattice vibrations of the exchange interaction.
